Light source module for tri-axes rotational measuring triad system used in navigation system, has light source that is integrated in substrate to emit polarized light on photoconductive fibers

摘要

#CMT# #/CMT# The light source module (10) has a substrate (9) in which light source (11) is integrated. The polarized light from light source is provided on photoconductive fibers (31-33). Beam splitters (17,18) are provided for splitting polarized light from light source onto photoconductive fibers. A light source monitoring unit (14) is provided for monitoring the light emitted from light source provided between a light source monitoring unit and a polarizer (13). #CMT# : #/CMT# Independent claims are included for the following: (1) an integrated-optical coupler module; and (2) a tri-axes rotational measuring triad system. #CMT#USE : #/CMT# Light source module for use with integrated-optical coupler module in tri-axes rotational measuring triad system (all claimed) e.g. multi stage sensor system used in navigation system. #CMT#ADVANTAGE : #/CMT# The assembling of triad system can be simplified. The energy consumption of the light source module can be reduced. The cost of the triad system can be reduced. The generation of attenuation loss in couplers can be reduced. The propagation delay in light source module can be reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic views of the light source module. 9 : Substrate 10,20,30 : Light source module 11 : Light source 13 : Polarizer 14 : Light source monitoring unit 17,18 : Beam splitters 31-33 : Photoconductive fibers.
