Abstract

Along with rapid development of semiconductor, photodetector arrays (e.g. CCD) have offered the great promise of compact Optical Multichannel Analyzer (OMA) for spectrum fast measurements in a variety of applications. It deserves to pay attention to frequency response of electronic circuit in OMA, otherwise it will impair the spectrum resolving power of the analyzer. In this paper, we present a detailed frequency analysis of electronic circuit in OMA, and find that the frequency response should be met a severe condition, in which the cutoff frequency is much higher than the output frequency of photodetector arrays, to guarantee the resolution performing well in OMA.
