Rosette-scan tomographic single-pixel imager

Spin-scan tomographic scanning imagers utilise a reticle with a fixed number of thin slits and nutating optics, and have produced images and video at both infrared and optical wavelengths. However, the fixed nature of these systems reduces their versatility by restricting changes that can be made after manufacture. An alternative rosette-scan tomographic scanning imager based on similar concepts is proposed to overcome this limitation. A single thin-slit reticle is rotated to be perpendicular to the line scan angle of each rosette petal, thereby allowing tomographic reconstruction. The parameters of the proposed system can be dynamically changed to achieve different trade-offs between resolution and frame rate. Initial results obtained from a proof-of-concept prototype demonstrate the feasibility of this approach. Rosette-scan tomographic scanning single-pixel imaging proposes an alternative to spin-scan tomographic scanning single-pixel imagers. The parameters of the proposed system can be dynamically changed to achieve different trade-offs between resolution and frame rate. Initial results obtained from a proof-of-concept prototype demonstrate the feasibility of this approach.image

Automated summary

Although spin-scan tomographic scanning imagers have limitations due to their fixed nature, an alternative rosette-scan tomographic scanning imager based on similar concepts allows for dynamic changes in parameters to achieve different trade-offs between resolution and frame rate. Initial results demonstrate the feasibility of this approach.
