Scanning single-pixel imaging with binary random structured illumination

A scanning single-pixel imaging method based on binary random structured illumination is proposed. The method employs a simple optical system and a binary spatial light modulator. The desired illumination intensity distribution can be generated at arbitrary planes through computational propagation of a binary random pattern, enabling image reconstruction at various depths and thus achieving three-dimensional imaging. In contrast to conventional computational ghost imaging, the proposed method achieves imaging by scanning a single binary random pattern, eliminating the need to regenerate a new pattern, to our knowledge, for each measurement. The effectiveness of the method is validated through numerical simulations and optical experiments. Additionally, the results demonstrate that increasing the number of pixels in the binary random pattern leads to improved image quality.
