Spectrum analysis has been shown as one of the most useful techniques in modern science.
Virtually every discipline makes use of it in one form or another. Generally, spectrum …

Why use optics for radio-frequency spectrum analysis, especially when electronic spectrum
analyzers are so good? There are several reasons: optical processing is inherently parallel; …

Spectrum analysis is one of the most fundamental tools in science today. Its use in one form
or another spans virtually every discipline. It was one of the first recognized applications of …

One of the most common measurement instruments found in a modern optics laboratory is
the optical spectrum analyzer (OSA). These instruments measure the optical power …

Coherent optical spectrum analyzers are available for determining the frequency content of
many analog signals written simultaneously on film. The space bandwidth product of each …

In this paper the possibility of optical pulses spectral measurement using optical fiber as a
dispersive system is examined. We study obtaining sample spectra which are new to optical …

A hybrid optical approach to coherent spectrum analysis realizes gains associated with time-
integrating techniques while still retaining some of the advantages of space-integrating …

The dramatic impact of the electronic integrated circuit upon virtually every kind of system
has provided the justification for efforts directed at developing integrated optical circuits …

Optical spectrographic processing systems have been shown to be the most widely used
techniques for time-varying signals that usually contain very distinct characteristics in …

In comparing two time signals, it is often necessary to perform synchronous Fourier
transformation on the signals. For example, in order to measure the propagation time delay …
