Abstract

Embodiments relate to compressive line sensing imaging. Initially, a codebook is configured with a pattern sequence for a series of illumination patterns. Each light element in an individually addressable laser diode array (IALDA) is independently controlled to project the series of illumination patterns onto a target. Next, measurements of the target are acquired based on the series of illumination patterns. The codebook is then used to decode the measurements to create an image of the target.
