单像素探测成像实验研究

Experimental imaging study using single-pixel detector

提出了不需要使用任何几何光学成像系统的单像素探测成像方法并进行实验研究.通过投影一系列不同频率组合、且每种频率组合具有4种不同初相位的二维正弦灰度条纹到成像物体表面,利用单像素探测器探测来自成像物体的后向散射光,然后对成像物体的频谱进行重建.本文给出详细的理论基础、实验装置和实验结果.

A novel imaging method,which used a single-pixel photodiode without any geometrical imaging system,was presented and experimentally studied.By projecting a series of two-dimensional periodic sinusoidal patterns of different frequencies,for each pattern of the same frequency,there had four different initial phases,namely,the back scattering light from the imaged object was detected using the single-pixel photodiode,and then the spectrums of the imaged object were reconstructed.The imaging theory was derived in detail.The experimental set-up was introduced and the experimental results were demonstrated.
