Research on Measurement of Spectral Radiance for (230-1700)nm Transient Radiation Source
Photonics and Optoelectronic（2010）
摘要
A spectral radiance measurement device is presented for (230-1700) nm transient radiation source. This device consists of a high temperature black body, two off-axis parabolic mirror, a reference radiation, a grating spectrograph and array CCD detector system. The measure principle model is described. In order to improve the measure precision for UV and NIR nanosecond transient radiation, we adjust the CCD integral periods and adopt the fixed phase high speed signal collection method to enhance the SNR of the device. Simultaneously the spectral distortion of the spectrograph is eliminated using non-parametric kernel regression de-noising algorithm and convolution algorithm. Some experiment results are also presented and discussed in this paper.
