Abstract

The use of optical processing for spectrum analysis is discussed with reference to space integrating and time integrating techniques. The space integrating techniques discussed include radiometry for detecting low-level signals in wide-band noise, programmable filtering of electrical signals for interference rejection applications, and an optical technique that is equivalent to one million parallel filters for applications where fast response, high resolution, and wide bandwidth of coverage are required. Time integrating techniques are discussed in terms of time integrating correlators and distributed oscillators. Consideration is given to the use of one-dimensional optical components configured for performing two-dimensional operations.
