Abstract

The invention relates to a space optics double-camera continuous imaging uniform-speed swinging movement device, belongs to the device involved in the technical field of space optic imaging, and aims at solving the technical problem of providing the double-camera continuous imaging uniform-speed swinging movement device. According to the technical scheme for solving the problem, the device comprises a swinging drive motor, a worm, a worm wheel, a reversing spring, a reversing cam, a reversing motor, a reversing platform, five rotating shafts, four swinging cams, two swinging springs, two push rods, two cameras and the like. Through the swinging drive motor, the worm wheel and the worm are driven to rotate to bring the swinging cams into rotation, and the swinging cam rotates, and through the push rods, drives the two cameras into constant speed reverse swinging movement. The device has the beneficial effect that through driving the two sets of swinging cams by one motor, uniform-speed and symmetrical swinging imaging of the two cameras with the same speed and in opposite directions is realized, thereby avoiding disturbing moment effect during switching of motor forward and reverse rotation and greatly reducing moment disturbance to a satellite platform.

Description

Technical field: [0001] The invention belongs to a device capable of realizing a uniform swing sweep movement for continuous imaging of dual cameras and relates to the technical field of spatial optical imaging. Background technique: [0002] Optical cameras can be divided into swing scan imaging and staring imaging from the imaging method. The swing scan imaging camera adopts the time integration delay photo-charge coupled device (TDI CCD) delay integration method to superimpose the images of multiple linear array exposures. To obtain the final image, the pendulum scanning imaging mechanism is the prerequisite for the TDI CCD camera to obtain continuous images, and can provide special motions according to the imaging needs. [0003] At present, the space optical camera realizes the imaging integration of the camera along the orbit direction through the relative movement of the satellite and the earth, and the imaging range of the camera is determined by the field of view of the op...
