Broadband spectrometer with fiber optic reformattor.

摘要

The invention provides a system having a broadband spectrometer 20 with a fiber optic reformattor 16 for field use in detecting and identifying gas clouds within a field of view. The system includes a grating type spectrometer 20, a fiber optic reformattor 16, a focal plane detector array 24 and electronics 42-52 for background signal substraction techniques for generating spectral signature data which is analyzed for gas detection and outputting a decision making signal for recognition.
