Embodiment Construction

[0025] The rotary modulation type multi-mode high-efficiency microscanner is mainly composed of a rotating disk 17 containing flat optical elements, a fixed plate 15, a coupling 16, a photocoupler 12 for generating synchronous signals, a servo motor 19 and its drive circuit 18, etc. Such as figure 1 As shown, the rotating disk is roughly divided into three parts: the inner zone, the middle zone and the outer zone. There is a flange 1 connected to the servo motor 19 in the inner area, and three rectangular through holes 2 at 120° are arranged on the flange for use when the coupling 16 is assembled; the middle area is the area for installing flat plate components, and the area is divided into A number of windows 3 consistent with the shape of the flat element, with narrow support strips between the windows; the outer area is the edge area, the thickness is smaller than that of the middle area, and there is a small hole 4 for synchronous signal generation on it, and each window o...

Abstract

The invention discloses a rotary demodulation type multi-mode high-efficiency microscanner, which comprises a strong rotating disk, a retaining plate, an actuating motor, an actuating motor driving circuit, a coupler and a photoelectric coupler, wherein the rotating disk arranged between an optical lenses and an array detector and panel components on the rotating disk are driven to rotate by the actuating motor, the panel components sequentially cut in a light path to ensure that positions of images change a little, so that a microscanning image is obtained, a synchronizing signal is generated, and all optical images obtained through microscanning are transformed into electronic images; and the electronic images are arranged according to space positions by using frames as units in a process of processing the synchronizing signal and finally synthesized into a high-definition image, thus microscanning imaging is completed.

Description

technical field [0001] The invention relates to the technical field of micro-scanning imaging, in particular to a rotationally modulated multi-mode high-efficiency micro-scanner which makes optical images move slightly according to a predetermined pattern. Background technique [0002] The image resolution of the staring imaging system is limited by the size of the detector array, and it is difficult to improve. The micro-scanning imaging technology can improve the image resolution without changing the size of the detector array and the structure of the optical system, so it has very important application value. There are two main types of micro-scanning imaging: electronic micro-scanning imaging and optical micro-scanning imaging. Electronic micro-scanning imaging relies on image processing algorithms to insert pixels between the original image pixels to make the image smoother and more delicate, but there is no substantial improvement in transmission. Optical micro-scanni...
