The first question they face is how to detect an ultimately weak optical signal. This book gives the answer to this most important question. All the main types of photodetectors are considered, from photodiodes (including avalanche photodiodes) to focal plane arrays (FPA). Methods of matching photodetectors with preamplifiers are described. The pair photodetector plus preamplifier is treated as an integrated detection system. Much attention is paid to different types of noise and ways of maximising the signal-to-noise ratio (SNR). Foundations of theory of optimal filtering of photosignals are discussed taking due account of typical shapes of optical signals and noise spectra. Methods for tuning quasi-optimal filters to maximise the SNR are explained. The main problems associated with detection of low-level optical signals are considered: operation of avalanche photodiodes in photon count mode, filtering in the case of charge accumulation in FPA cells, and the effect of the number of pixels and geometry of FPAs on detection. Finally, using the examples of the laser range finder and IR Imager, we give guidelines for calculating the limiting parameters of optoelectronic systems to achieve the highest possible SNR. The book is based on many years' experience by the author and his colleagues in the development of photodetectors and FPAs. The book is aimed at research workers, engineers, students and postgraduates.

New waveguide effects are considered on the basis on various variants for self-focusing of the living cells of aquatic plant by laser beam irradiation.Показать полностьюNew waveguide effects are considered on the basis on various variants for self-focusing of the living cells of aquatic plant by laser beam irradiation. It is studying the process of forming of the ‘living multy-mode fiber-optic’ into the road of laser’s beam in water with motion of green living cells. Analysis gives that the wide set of different profiles of the refractive index in this ‘living optical fiber’ could be easy produced depending the frequency of applied lasers. Optical waveguide approach gives high sensitivity in living layer readout and control, this waveguides could be apply to environmental processing or for a cell’s studying, also different medical application could be realized according described mechanism.

Intended for use as both a senior and graduate level textbook and as a reference for workers in the field, it combines a solid treatment of optical signal processing theory with detailed descriptions of selected processing applications.Показать полностьюIntended for use as both a senior and graduate level textbook and as a reference for workers in the field, it combines a solid treatment of optical signal processing theory with detailed descriptions of selected processing applications. With a focus on processing two-dimensional analog signals, it treats the important new area of acousto-optic signal processing. Beginning with an examination of optical signal processing fundamentals, chapters cover basic signal parameters, geometrical optics, physical optics, spectrum analysis and spatial filtering. Later chapters, focusing on applications, examine heterodyne systems, heterodyne spectrum analysis, decimated arrays and cross-spectrum analysis, heterodyne transform and signal excision, space integrating correlators, time integrating systems and two-dimensional processing.

This is a practical approach to introductory laser electronics that emphasizes real-world applications and problem-solving skills over theory, providing a clear understanding of both optical and microwave frequencies.

In the continuing push toward optical computing, the focus remains on finding and developing the right materials. Characterizing materials, understanding the behavior of light in these materials, and being able to control the light are key players in the search for suitable optical materials.Показать полностьюIn the continuing push toward optical computing, the focus remains on finding and developing the right materials.

Optics in Magnetic Multilayers and Nanostructures presents an accessible introduction to optics in anisotropic magnetic media. While most of the literature presents only final results of the complicated formulae for the optics in anisotropic media, this book provides detailed explanations and full step-by-step derivations that offer insight into the procedure and reveal any approximations. Based on more than three decades of experimental research on the subject, the author explains the basic concepts of magnetooptics; nonreciprocal wave propagation; the simultaneous effect of crystalline symmetry and arbitrarily oriented magnetization on the form of permittivity tensors; spectral dependence of permittivity; multilayers at polar, longitudinal, transverse, and arbitrary magnetization; the effect of normal or near-normal incidence on multilayers; and anisotropic multilayer gratings. Making the subject of magnetooptics and anisotropic media approachable by the nonspecialist, Optics in Magnetic Multilayers and Nanostructures serves as an ideal introduction to newcomers and an indispensable reference for seasoned researchers.

In the early chapters the formalism of quantum optics is elucidated and the main techniques are introduced. These are applied in the later chapters to problems such as squeezed states of light, resonance fluorescence, laser theory, quantum theory of four-wave mixing, quantum non-demolition measurements, Bell’s inequalities, and atom optics. Experimental results are used to illustrate the theory throughout. This yields the most comprehensive and up-to-date coverage of experiment and theory in quantum optics in any textbook

Walter T.Показать полностьюStudents and professionals alike have long felt the need of a modern source of practical advice on the use of optical tools in scientific research. Walter T. Welford’s Useful Optics meets this need. Welford offers a succinct review of principles basic to the construction and use of optics in physics. His lucid explanations and clear illustrations will particularly help those whose interests lie in other areas but who nevertheless must understand enough about optics to create the experimental apparatus necessary to their research. Consistently emphasizing applications and practical points of design, Welford covers a host of topics: mirrors and prisms, optical materials, aberration, the limits of image formation and resolution, illumination for image-forming systems, laser beams, interference and interferometry, detectors and light sources, holography, and more. The final chapter deals with putting together an experimental optics system. Many areas of the physical sciences and engineering increasingly demand an appreciation of optics. Welford’s Useful Optics will prove indispensable to any researcher trying to develop and use effective optical apparatus. Walter T. Welford (1916-1990) was professor of physics at Imperial College of Science, Technology and Medicine from 1951 until his death. He was a Fellow of the Royal Society and of the Optical Society of America.

В ней последовательно рассматриваются методы получения голограмм, восстанавливающих изображения, а не волновые фронты, как обычные голограммы. Эти методы базируются на топографической регистрации интерференционного поля в плоскости изображения объекта и состоят в проведении восстановления немонохроматическим излучением, использовании протяженного опорного источника, регистрации в многомодовом лазерном излучении с диффузным рассеянием опорной волны. Регистрация сфокусированных изображений с опорным пучком и без него позволяет реализовать два метода интерференционных измерений — соответственно топографическую интерферометрию сфокусированных изображений и спекл — интерферометрию. В основе спекл-интерферометрии лежит регистрация сфокусированных изображений предметов в диффузно, рассеянном когерентном излучении, т.е. получение изображений, модулированных спекл-структурой. Спекл-интерферометрия, развивающаяся во многом под влиянием голографической интерферометрии, в последнее время начинает оказывать на нее ответное влияние. В частности, в книге показывается, что использование в голографии и голографической интерферометрии приемов пространственной фильтрации, характерных для практики спекл-интерферометрии, открывает новые возможности обработки изображений и интерпретации голографических интерферограмм. Для научных работников и инженеров, занимающихся голографией и ее приложениями, специалистов смежных областей, заинтересованных в использовании когерентно-оптических и голографических методов, а также аспирантов и студентов старших курсов соответствующих специальностей.

В том 2 вошли главы 9 и 10, в которых рассматриваются отдельные проблемы голографии и области ее применения. В книге содержится множество новейших справочных данных, что делает ее замечательным практическим руководством для специалистов, применяющих голографические методы.

В том 1 вошли главы 1—8, посвященные разделам науки, на основе которых разрабатывается голография, а также вопросам теории и формирования голограмм; подробно рассматривается использование лазеров и сред для записи голограмм.
