MONOLITHIC INFRARED SPECTROMETER APPARATUS AND METHODS

摘要

A monolithic spectrometer system providing vibration immunity and thermal stability, designed for infrared gas detection and chemical identification in the field or on the loading dock. One embodiment of the invention includes a spectrometer system (10) with the following elements: a silicon block waveguide (12); a cylindrical mirror (14); a diffraction grating (16); and a linear detector array (18). Electronics (20) can couple to the array (18) so as to collect electronic data representative of the spectral characteristics of the light (22) entering the system (10). Control of the system (10) is obtained through user interface (24). A battery (26) can be used to power the system (10).
