A full-frame transfer type ccd camera inter-lens shutter device

Abstract

The invention discloses a full-frame transfer type CCD camera inter-mirror shutter device, comprising: a cover, an outer shell, an inner shell, a conductive coil assembly, an angle aluminum 1, an angle aluminum 2, a moving shaft, a rivet 1, a moving plate, a rivet 2, Slip rings, blades, rivets 3 and fixing screws; the blades are located between the outer casing and the inner casing, and have a fulcrum fixed on the outer casing to ensure that the blade can rotate around the fulcrum, and the other fulcrum of the blade passes through the inner casing and the inner casing through the rivet 3 The slip ring is connected; one end of the moving plate is connected to the slip ring through a rivet 2, the other end is connected to the moving shaft through a rivet 1, the moving shaft is connected to the conductive coil assembly, and the conductive coil assembly is fixed on the inner shell through the angle aluminum 1 and the angle aluminum 2; The cover and the housing are fixed together by two fixing screws; among them, the blades in the shutter device are located at the position of the aperture stop between the front mirror group and the rear mirror group. The shutter device has the advantages of small size, light weight, high efficiency and long life.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a full-frame transfer type CCD camera inter-mirror shutter device. Background technique [0002] With the rapid development of the aviation industry, aerial imaging technology has been widely used in military and civilian fields, such as military target detection, ground surveying and mapping, ground target tracking and so on. With the continuous improvement of camera technical specifications, there is an urgent need for the emergence of large area array and wide field of view cameras. The full-frame transfer type area array CCD is simple in structure, has a large number of pixels, and a large fill factor, which meets the large area array requirements of the camera system and has been widely used in the field of aerial imaging. However, after photoelectric conversion, since there is no image storage area, the photocharges are transferred row by row to the horizontal shift regis...

Problems solved by technology

[0005] The objective lens shutter has low efficiency, high energy consumption, and is easy to vibrate, which affects the imaging quality. It is difficult to reduce the exposure time of large-aperture optical cameras, and the service life is short during continuous operation.
