Embodiment Construction

[0037] A single-pixel tomographic scanning device based on time-division amplitude modulation

[0038] A single-pixel tomographic scanning device based on time-division amplitude modulation proposed in this embodiment includes: an imaging detector 8 and an image rotation device 3 sequentially arranged on the optical path from the imaging surface of the object to be imaged 1 to the imaging detector 8, Cylindrical lens 5 and first focusing lens 7. That is, in the direction of light propagation, the imaging surface of the object to be imaged faces the image rotation device 3, and the object to be imaged, the image rotation device 3, the cylindrical mirror 5, the first focusing lens 7 and the imaging detector 8 are sequentially along the direction of light propagation layout.

[0039] The image rotation device 3 is used to rotate the incident projected image to generate a rotated image.

[0040] The cylindrical mirror 5 is used for one-dimensional integral amplification of the i...

Abstract

The invention discloses a single-pixel tomography scanning device based on time-division amplitude modulation. The single-pixel tomography scanning device comprises an imaging detector, and an image rotating device, a cylindrical mirror and a first focusing lens which are sequentially arranged on a light path from an imaging surface of an object to be imaged to the imaging detector. According to the invention, the first focusing lens is arranged between the cylindrical mirror and the imaging detector, so that the rotating image passing through the cylindrical mirror is focused by the first focusing lens and then projected to the imaging detector, and the rotating image is completely located in the detection area of the imaging detector; therefore, the acquisition of the projection image of the object to be imaged in the static state of the imaging detector is realized.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a single-pixel tomographic scanning device based on time-division amplitude modulation. Background technique [0002] Object detection and tracking is a research topic of great interest to people all the time. In order to pursue a better target detection effect, the detection of target imaging technology has always attracted much attention. Existing imaging detection devices are mostly used in parallel light environments, and the resolution in natural light environments is far from ideal. [0003] Moreover, in the existing imaging detection technology, the detection area of ​​the imaging detector is small, and it is difficult to cover the field of view of the image side, and the acquisition of a complete projection image can only be ensured by the movement of the imaging detector. The movement of the imaging detector will easily cause the collected projection image to shake, which will a...
