Evaluation of Resolution Improvement Ability of a DSP Technique for Filter-Array-Based Spectrometers
The Journal of Korean Institute of Communications and Information Sciences(2013)
摘要
In this paper, we aim to evaluate the performance of the digital signal processing (DSP) algorithm used in [8] in order to improve the resolution of spectrometers with fixed number of low-cost, non-ideal filters. In such spectrometers, the resolution is limited by the number of filters. We aim to demonstrate via new experiments that the resolution improvement by six times over the conventional limit is possible by using the DSP algorithm as claimed by [8].
