【Abstract】 The experimental setup was constructed with a 300 W high stability Xenon lamp,fore condenser lens,concave grating flat-field monochromator,programmable digital micromirror device( DMD),post condenser lens and integrating sphere. The test experiments of light source spectral radiances were carried out and the measurement results of spectral radiances of light source in broadband and narrow-band modes were obtained. The developed experimental unit of spectrally tunable light source can produce optical radiation with different spectral distributions as needed by programmable manipulations,and the operability of programmatically changing spectral distributions of light source was indicated.更多还原
