为在激光显示中实现白场色温的实时控制,根据CIE1931和CIE1964标准色度系统计算了激光显示三基色光源(R 638 nm,G 520/532 nm,B 450 nm)形成5500~7500 K色温的混合白光时的光功率配比,探讨了三基色光源的光功率比例、中心波长以及光谱宽度对混合白光色温、色品坐标和光通量的影响。设计了基于AS73211颜色传感器的实时光反馈色温控制系统,并在模拟激光显示装置中于5500~7500 K范围内实现了误差小于±50 K的色温控制精度。

Fano resonances are conventionally understood as sharp spectral features with selectivity in the momentum-frequency domain, implying that they can be excited only by plane waves with specific frequencies and incident angles. We demonstrate that Fano reson
We evaluate and demonstrate ultra-broadband near-infrared noncollinear optical parametric amplification in two nonlinear crystals, bismuth borate (BiBO) and yttrium calcium oxyborate (YCOB), which are not commonly used for this application. The spectral b
