Patent ID: 7692785

Claim:
A system for managing optical power for controlling thermal alteration of a sample undergoing Raman spectroscopic analysis, the system comprising: a moveable laser beam generator for irradiating the sample, wherein the moveable laser beam generator comprises: at least one beam shaping device, wherein the at least one beam shaping device comprises at least one Micro-Electro-Mechanical Systems (MEMS) integrated circuit (IC); a moveable substrate platform; and a controller/analyzer for controlling the laser beam generator, the substrate platform, and for analyzing light reflected from the sample; wherein the MEMS IC comprises: at least one optical input; at least one optical output optically connected to the at least one optical input; at least one fiber Bragg grating disposed between the at least one optical input and the at least one optical output; a microheater array for adjusting the at least one fiber Bragg grating optical Properties; and a feedback control circuit connected to the microheater array, and wherein the feedback control circuit is connectable to the controller/analyzer.
