A Single-Pixel Imaging Scheme with Obstacle Detection

Single-pixel imaging (SPI) utilizes a second-order correlation of structured illumination light field and single-pixel detector to form images. As the provides no spatial resolution, generated by devices such as modulator substitutes role array camera retrieve pixel-wise information. Due its unique modality, SPI has certain advantages. Meanwhile, counterintuitive configuration reciprocity relation traditional cameras have been studied understand fundamental principle. According previous studies, non-spatial detection property makes it possible for resist scattering in part. In this work, we study influence an obstacle aperture part SPI. We notice that can restrict field-of-view (FOV) SPI, which be diminished process. investigate these properties with experiment results analysis under geometry optics. believe our will helpful understanding imaging.
