Supplementary material

This Supplementary Material expands upon the content presented in the main manuscript to offer detailed information about the imaging process and addresses several widely concerned issues. In this Supplementary Material, we cover the following topics: In Section 2, we provide supplementary derivations of our convolutional approximations for under-scanning non-line-of-sight (NLOS) imaging. In addition, we provide the derivation of the Poisson term. In Section3, we show how the parameters are chosen. In Section 4, we provide more details on the hardware prototype. In Section 5, we provide additional reconstruction results.
