We present a technique called single-pixel imaging camera based on complementary detection and optimized encoded modulation (CSPI camera), which can significantly reduce the influence of the disturbance light to single-pixel imaging (SPI). The experiments demonstrates that when the probability of the value "1" for each binary encoded pattern is P=0.5, CSPI camera is still disturbance-free even if the intensity fluctuation of the disturbance light is much larger than the signal's intensity. The reconstruction results of both traditional SPI and differential SPI are also compared. This technique of CSPI camera can dramatically promote real application of single-pixel imaging Lidar.
我们提出了一种基于互补检测和优化编码调制的单像素成像相机技术（CSPI相机），该技术可以显著降低干扰光对单像素成像（SPI）的影响。实验表明，当每个二进制编码图案的值“1”的概率为P = 0.5时，即使干扰光的强度波动远大于信号强度，CSPI相机仍然不受干扰。同时还比较了传统SPI和差分SPI的重建结果。CSPI相机的这种技术可以极大地推动单像素成像激光雷达的实际应用。
