Abstract

Spin-scan and conical-scan tomographic scanning (TOSCA) imagers have produced good-quality and costeffective images and video in both the infrared (IR) and optical wavelengths. A novel rosette-scan implementation of TOSCA single-pixel imaging is presented below. Previous conical-scan TOSCA imagers implemented a reticle with a fixed number of thin slits. This resulted in a fixed angular resolution which implied a fixed image resolution. The feasibility of a rosette-scan implementation using similar processing techniques to conical-scan TOSCA imagers will be demonstrated. The rosette-scan implementation would only require a reticle with a single thin slit, instead of a reticle with a number of thin slits at fixed angles. The single thin-slit reticle can be rotated to be perpendicular to the line-scan angle of each rosette petal. The number of scan angles can be dynamically changed to achieve different trade-offs between resolution and frame rate by varying the rotational speeds of the prisms and the single thin slit reticle.
