Patent ID: 8736919

Claim:
An imaging system, comprising: a detection unit, sensing radiation of a target area comprising a plurality of pixels; and a scan unit, directing the radiation from the target area to the detection unit, comprising: a refractive focus unit refracting and focusing the radiation; and a rotatable reflection plate reflecting the radiation, wherein the refractive focus unit and rotatable reflection plate are arranged such that the radiation originating from the target area is directed to the detection unit; wherein the refractive focus unit and the rotatable reflection unit are configured to sequentially direct the radiation of each of the pixels of the target area to the detection unit N times at a constant speed within a scan period, such that each of the pixels of the target area is scanned N times by the scan unit, wherein the detection unit is configured to generate N sub-detection values for each of the pixels according to the radiation respectively sensed in each of the N scans and add up the N sub-detection values of each of the pixels to generate a detection value for each of the pixels.
