We present the design and testing of a stochastic analog spatial light modulator designed for compressive imaging applications. This spatial light modulator does not require the external generation or input of the often computationally or memory expensive sampling matrices. We rely on the stochastic nature of multi-particle collisions to provide randomization for the particle location. We demonstrate this concept in an optical imaging system using a single-pixel camera. This design can be applied to imaging or spectroscopic systems in which no analog to optical spatial light modulators currently exist or in non-optical lensless imaging systems.
