Publication number: 20070171424Abstract: A spectrometer for use with a desired wavelength range includes an array of filters. Each filter outputs at least two non-contiguous wavelength peaks within the desired wavelength range. The array of filters is spectrally diverse over the desired wavelength range, and each filter in the array of filters outputs a spectrum of a first resolution. An array of detectors has a detector for receiving an output of a corresponding filter. A processor receives signals from each detector, and outputs a reconstructed spectrum having a second resolution, the second resolution being higher than any of the first resolution of each filter.Type: ApplicationFiled: March 19, 2007Publication date: July 26, 2007Applicant: DIGITAL OPTICS CORPORATIONInventors: Robert Te Kolste, Alan Kathman

Publication number: 20060262816Abstract: A wavelength locker for use at more than one wavelength includes filters with different characteristics for a corresponding detector. The filters may be etalons having different free spectral ranges, e.g., having different apparent or real thicknesses. If more than three such filters are used outputting offset periodic signals, a reference detector may be eliminated and continuous operation over a wavelength range may be realized.Type: ApplicationFiled: July 25, 2006Publication date: November 23, 2006Applicant: DIGITAL OPTICS CORPORATIONInventors: Alan Kathman, John Hammond, Robert Te Kolste, Alvaro Cabrera
