ABSTRACT:
A wideband optical micro-spectrometer system for detecting the intensity of light as a function of wavelength. The device employs multiple optical micro-spectrometers generating adjacent spectra mounted onto a single photodetector array and digital processing techniques to generate a continuous wide spectrum from the narrower spectrums generated by the optical micro-spectrometers. Optical micro-spectrometers generating non-adjacent spectra could also be employed to produce spectral data for predetermined non-adjacent spectral ranges. System reliability is improved and maintenance reduced with the use of pre-aligned optical micro-spectrometers. Thereby, a device is created which has the spectral range of larger spectrometers having a much reduced physical size, increased system reliability and reduced maintenance requirements.
