Detection of Optical and Infrared Radiation (Springer Series in Optical Sciences) (Volume 10)
Detection of Optical and Infrared Radiation (Springer Series
This text treats the fundamentals of optical and infrared detection in terms of the behavior of the radiation field, the physical properties of the detector, and the statistical behavior of the detector output. Both incoherent and coherent detection are treated in a unified manner, after which selected applications are analyzed, following an analysis of atmospheric effects and signal statistics. The material was developed during a one-semester course at M.I.T. in 1975, revised and presented again in 1976 at Lincoln Laboratory, and rewritten for publication in 1977. Chapter 1 reviews the derivation of Planck's thermal radiation law and also presents several fundamental concepts used throughout the text. These include the three thermal distribution laws (Boltzmann, Fermi-Dirac, Bose Einstein), spontaneous and stimulated emission, and the definition and counting of electromagnetic modes of space. Chapter 2 defines and analyzes the perfect photon detector and calculates the ultimate sensitivity in the presence of thermal radiation. In Chapter 3, we turn from incoherent or power detection to coherent or heterodyne detection and use the concept of orthogonal spatial modes to explain the antenna theorem and the mixing theorem. Chapters 4 through 6 then present a detailed analysis of t...

Optics for Engineers
The field of optics has become central to major developments in medical imaging, remote sensing, communication, micro- and nanofabrication, and consumer technology, among other areas. Applications of optics are now found in products such as laser printers, bar-code scanners, and even mobile phones. There is a growing need for engineers to understand the principles of optics in order to develop new instruments and improve existing optical instrumentation. Based on a graduate course taught at Northeastern University, Optics for Engineers provides a rigorous, practical introduction to the field of optics. Drawing on his experience in industry, the author presents the fundamentals of optics related to the problems encountered by engineers and researchers in designing and analyzing optical systems. Beginning with a history of optics, the book introduces Maxwell’s equations, the wave equation, and the eikonal equation, which form the mathematical basis of the field of optics. It then leads readers through a discussion of geometric optics that is essential to most optics projects. The book also lays out the fundamentals of physical optics―polarization, interference, and diffraction―in sufficient depth to enable readers to solve many realistic problems. It continues the discussion...

Phase error statistics of a phase-locked loop synchronized direct detection optical PPM communication system
Phase error statistics of a phase-locked loop synchronized
Receiver timing synchronization of an optical Pulse-Position Modulation (PPM) communication system can be achieved using a phased-locked loop (PLL), provided the photodetector output is suitably processed. The magnitude of the PLL phase error is a good indicator of the timing error at the receiver decoder. The statistics of the phase error are investigated while varying several key system parameters such as PPM order, signal and background strengths, and PPL bandwidth. A practical optical communication system utilizing a laser diode transmitter and an avalanche photodiode in the receiver is described, and the sampled phase error data are presented. A linear regression analysis is applied to the data to obtain estimates of the relational constants involving the phase error variance and incident signal power. Natarajan, Suresh and Gardner, C. S.
