  Acoustic imaging typically relies on large sensor arrays that can be
electronically complex and often have large data storage requirements to
process element level data. Recently, the concept of a single-pixel-imager has
garnered interest in the electromagnetics literature due to it's ability to
form high quality images with a single receiver paired with shaped aperture
screens that allow for the collection of spatially orthogonal measurements.
Here, we present a method for creating an acoustic analog to the
single-pixel-imager found in electromagnetics. Additionally, diffraction is
considered to account for screen openings comparable to the acoustic
wavelength. A diffraction model is presented and incorporated into the single
pixel framework. The method is experimentally validated with laboratory
measurements made in air.
