Procedure and optical microfabricated device for detection of absorption bands / emission in infrared.

摘要

FACILITATES DETECTION AND CHEMICAL SUBSTANCES WITH RADIATION EMITTING costs well below those of known systems and with sufficient accuracy for many applications such as gas detection in mixtures. The procedure involves GENERATING A RADIATION THAT IS FLAT IN A FEATURE OF THE SUBSTANCE SOURCE TO DETECT AND CROSSING BANDA AN ENVIRONMENT IN WHICH SUCH SUBSTANCE IS, AFTER effected modulation RADIATION AND A SENSE OF RADIATION MODULATED will bring a signal directly related to the concentration of the substance in said ENVIRONMENT. The corresponding device includes a lamp (1) that adjusts an optical (2) guide so that it lights O radié ENVIRONMENT UNDER STUDY; Provided ENFRENTADAMENTE to said guide (2) a detector (4), E intercalated between BOTH a modulator (3).
