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.en© 2023 The Authors. Electronics Letters.
