We present the effects of using a single-pixel camera approach to extract optical properties with the single-snapshot spatial frequency-domain imaging method. We acquired images of a human hand for spatial frequencies ranging from 0.1 to 0.4 mm - 1 with increasing compression ratios using adaptive basis scan wavelet prediction strategy. In summary, our findings indicate that the extracted optical properties remained usable up to 99% of compression rate at a spatial frequency of 0.2 mm - 1 with errors of 5% in reduced scattering and 10% in absorption.
我们展示了使用单像素相机方法来提取光学特性的效果，该方法采用单次快照空间频域成像方法。我们使用自适应基扫描子波预测策略，获取了人类手部在 0.1 至 0.4mm-1 空间频率范围内的图像，压缩比逐渐增大。总的来说，我们的研究结果表明，在 0.2mm-1 的空间频率下，提取的光学特性在高达 99%的压缩率下仍然可用，其散射减少误差为 5%，吸收减少误差为 10%。
