Problems solved by technology

However, the universal stable platform has restrictions on the weight and design size of imaging instruments. For example, the universal stable platform PAV30 produced by Swiss Leica Company has a payload limit of 100Kg±3Kg and an installation size of 436mm, which cannot meet imaging instruments of different weights and dimensions. needs

Embodiment Construction

[0024] Combine below figure 1 A better example of the present invention is given, which is mainly described in further detail, but not used to limit the scope of the present invention:

[0025] When the present invention is applied to an area array imager, it is required to realize 55° wide-field imaging in the direction of the wingspan. According to the size of the area array imager, the rolling gimbal is designed, the imager is fixed on the rolling girdle, and then the base is designed, and the aluminum alloy material is selected to process the base and the rolling girdle. The flat glass mirror is selected as the 45° compensation mirror, the swing-angle voice coil motor is selected as the motor of the roll axis and the pitch axis, and the 45° compensation mirror and the pitch axis voice coil motor form the pitch ring frame.

[0026] Using the classic PID three-loop (position loop, speed loop, current loop) control algorithm in the control field, the roll axis voice coil mot...

Abstract

The invention discloses a wide view field imaging structure for recombining stabilized platform functions and a control method of the wide view field imaging structure. The wide view field imaging structure comprises a base, a transverse roll ring frame, a pitching ring frame, a transverse roll shaft motor, a pitching shaft motor, a 45-degree compensating mirror and an imaging instrument. A stabilized platform is recombined to the wide view field imaging structure, a classical PID three-ring control algorithm in the control field is adopted, wide view field swing imaging in the wing expanding direction and forward image motion compensation in the flying direction are achieved, the stabilized platform is configured to the imaging instrument, and the limit problems of the instrument weight and the design dimension caused by a general stabilized platform are effectively solved.

Description

technical field [0001] The invention relates to a wide field of view imaging structure, in particular to a wide field of view imaging structure capable of realizing wide field of view swing-sweep imaging in the wingspan direction and forward image motion compensation in the flight direction, and a control method thereof. Background technique [0002] Under the premise of image quality requirements, it is difficult to rely on single-lens non-scanning imaging to achieve wide field of view (over 30°) imaging. In the past when the area array detector technology was not yet mature, the acquisition of wide-field images was achieved by using a unit or line array detector, and using a rotating scanning mirror in front of the optical system to scan line by line in the span direction. With the development of area array detector technology, the way of wide-field imaging has changed accordingly. Today, as the area array detector technology is becoming more and more mature, the use of a...
