Abstract : A compact lens-less spectrum analyzer where a laser impinges upon a distributed Bragg deflector via a slab-coupled optical waveguide and is bent 90 degrees. A surface acoustic wave transmitter controlled by an R-F frequency puts on a traveling strain wave which deflects the light beam according to the frequencies present; a manifold of distributed Bragg deflectors receive the deflected signal and are so arranged as to resonate at a particular frequency; the output of the resonating Bragg deflector is detected by a CCD or self-scanning diode array which produces an output indicative of the particular frequency detected.
