Modeling and implementation of static-pattern single-pixel imaging for linearly moving objects via a low-cost...

Conventional single-pixel imaging (SPI) typically relies on expensive dynamic projectors or bulky moving parts, making its cost-effective implementation difficult in non-visible wavelength ranges. In this paper, we propose a compact, low-cost, and entirely solid-state single-static-pattern SPI (SSPI) system for moving objects. Our system employs a wavelength-independent metal-plate mask with microholes to generate illumination patterns, eliminating the need for dynamic projection devices. We carefully model the unique constraints of this configuration, such as image resolution and background reflection, and propose effective mitigation methods. Experimental demonstrations in the visible range confirm the effectiveness of the system. We also verify the mask's functionality in the short-wave infrared (SWIR) range, highlighting its potential for non-visible applications.
