Remote Sensing by Fourier Transform Spectrometry by Reinhard Beer,

Remote Sensing by Fourier Transform Spectrometry by Reinhard Beer,
While there have been many books dealing with the instrumental and mathematical processing aspects of Fourier Transform Spectroscopy there remains a need for a text which examines the technique as a remote-sensing tool. Remote Sensing by Fourier Transform Spectrometry fills that gap to offer students and professionals in a variety of fields a comprehensive reference on the application of FTS to their research needs. Remote Sensing by Fourier Transform Spectrometry serves as an introduction to the specification, design, and implementation of Fourier Transform Spectrometers (FTS), especially those intended for atmospheric or astronomical remote sensing. Beginning with an overview of the phenomenon of two beam interference, the book introduces the reader to some of the terminology and units characteristic of this specialty. The book goes on to investigate the performance of the Michelson Interferometer as a Fourier Transform Spectrometer. A solid introduction to the chemistry and physics of remote sensing, including a simplified development of the theory of radiative transfer, is also provided. A detailed section of real Fourier Transform Spectrometers begins with a discussion of the estimation of signal-to-noise ratio using radiometric models, including the impact of pointing jitter or signal fluctuation on an FTS-generated spectrum. An analysis of the theory and practice of interferogram sampling is followed by a section on how certain modifications to the simple Michelson Interferometer can provide optical configurations more suited to the stresses of remote sensing. The final portion of this section describes potential problem areas in the implementation of an FTS, such as phaseerrors, channeling, and linearity.

The Fractional Fourier Transform: With Applications in Optics and Signal Processing by Haldum M. Ozaktas,
"The Fractional Fourier Transform" provide a comprehensive and widely accessible account of the subject covering both theory and applications. As a generalisation of the Fourier transform, the fractional Fourier transform is richer in theory and more flexible in applications but not more costly in implementation. This text consolidates knowledge on the transform and illustrates its application in diverse contexts. Applications studied so far fall mostly in the areas in optics and wave propagation and signal processing, including optical information processing, beam synthesis, phase retrieval, perspective projections, shift-variant filtering, image restoration, pattern recognition, tomography, data compression and time-frequency representations. Background material introduces time-frequency analysis emphasizing the Wigner distribution, ambiguity function and canonical transforms. Chapter on phase-space optics employs matrix algebra in a unified manner for both wave and geometrical optics, leading to many important results such as those on general Fourier transform planes and optical invariants. Separate discussion of optics for readers with no interest in optics. Unifying knowledge from the mathematics, optics and signal processing literature in a manner accessible to a broad audience, this book is of interest to researchers, engineers, and senior undergraduate and graduate students in electrical engineering, physics, and mathematics.



Fractional Fourier transform - The fractional Fourier transform (FRFT) is a linear transformation generalizing the continuous Fourier transform, which can be thought of as the Fourier transform to the n-th power where n need not be an integer — thus, it can transform a function to an intermediate domain between time and frequency. Its applications range from filter design and signal analysis to phase retrieval and pattern recognition.

Multiplier (Fourier analysis) - In Fourier analysis, a Fourier multiplier (or multiplier for short) is a kind of linear operator, or transformation of functions. These operators multiply the Fourier coefficients of a function by a specified function (known as the symbol), hence the name.

Hadamard transform - The Hadamard transform (Hadamard transformation, also known as the Walsh-Hadamard transformation) is an example of a generalized class of Fourier transforms. It is named for the French mathematician Jacques Hadamard.

Paley–Wiener theorem - In mathematics the Paley–Wiener theorem relates growth properties of entire functions on Cn and Fourier transformation of Schwartz distributions of compact support.
