Abstract

The invention discloses a focal plane mechanical shutter for an aerial camera, comprising: a continuous tightening mechanism, an exposure control mechanism, and a photographing signal acquisition mechanism. The invention also provides an optical device. The focal plane mechanical shutter for an aerial camera provided by the present invention can control the high-frequency continuous exposure action of the shutter, and can precisely adjust the exposure time, exposure amount and exposure working frequency of the shutter.

Description

technical field [0001] The invention belongs to the technical field of aerial imaging, and in particular relates to a focal plane mechanical shutter and an optical device for an aerial camera. Background technique [0002] The aerial camera obtains the target image through the optical system, and uses the imaging medium such as film or CCD to record the image information. Get clear images. Aerial cameras use shutters to achieve the above controls. In order to meet the needs of acquiring a large amount of rich target image information in a short time, the surface of the imaging medium is required to be enlarged. However, the existing central mechanical shutter cannot meet the above requirements. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a focal plane mechanical shutter capable of realizing large-format high-frequency continuous imaging control. The present invention adopts following technical scheme: ...
