Abstract
A modified (frequency-shifted) Michelson interferometer uses a laser, an acoustooptic cell, and a movable mirror to produce a wide-band FM signal having a center frequency of 80 MHz. The basic concepts are reviewed, and a report of an operating system is given. The angle modulation scheme may be used to produce very wide-band FM or PM. Systems configurations are explored that allow several communication channels in a frequency-division multiplexing arrangement.
