Document Type and Number:
Japanese Patent JPH06502483
Kind Code:
A
Abstract:
An optical spectral analyzer (10) for receiving an input beam (30) through a multi-mode optic fiber (28). The input or beam (30) has a predetermined spectral band width. The random individual spectral components of the beam (30) are dispersed by a grating (40) to generate a spectrum (42, 42' . . . 42N). A detector (52) senses the magnitude of the elements in a reflected focused spectrum (50, 50' . . . 50N) to recover the information placed on the optic fiber (28) at a remote location by a spectrum encoding device.
