title: [Measurement of night sky spectral radiation and analysis of spectral denoising].
abstract: In spectral radiation detection, spectral characteristics of the environment are completely different from standard light sources, so the output characteristics of optical imaging device is bound to bring greater error due to spectrum matching in imaging characteristic analysis. In the present paper, we measured moon-light and star-light spectral radiation using a portable CCD fiber spectrometer, and analyzed spectral characteristics, which provided a reference to correctly evaluate the imaging performance of optical imaging device.
