An optical spectrum analyzer based on optical processing of the far field interference pattern from two beams irradiated by light transmitting waveguides is described. The spectrum analyzer can operate in UV, VIS, NIR and MIR ranges of spectrum and it can be based on either optical fibers (multimode or single-mode) or integrated optical waveguides. It has many important applications, for example, as a simple, compact and inexpensive spectrum analyzer used with fiber optic chemical and biological sensors.
