Abstract

Single-pixel imaging (SPI), utilizing spatial encoding and single-pixel detection to reconstruct visual information, offers a substantial advantage in hardware simplicity and cost efficiency. This study presents a differential SPI system based on a rotating encoded disk, employing dual detectors to exploit the reflection and transmission of the disk for real-time imaging. Simultaneously, audio signals modulated onto the light source were successfully recovered at a distance of about 2 m. The proposed method inherently synchronizes image and audio data without additional communication modules (such as Wi-Fi), ensuring covertness and security. This dual-modal sensing approach demonstrates significant potential for real-time, high-fidelity applications in complex scenarios.
