The invention provides a curtain type shutter exposure uniformity detection device, and relates to the field of aerospace imaging. The problem that an existing simple detection device can not meet requirements on curtain type shutter exposure uniformity detection can be solved. The curtain type shutter exposure uniformity detection device comprises a camera obscura, wherein a control circuit board and a shutter release button are respectively fixed at the upper end and the lower end outside the camera obscura, a shutter, a light source component and a photocell component are mounted in the camera obscura, the light source component comprises a lens hood connected with the control circuit board, a first supporting plate with a through hole is arranged at the inner lower end of the lens hood, a light source is fixed on the control circuit board in the lens hood, a collimating lens is fixed in the through hole in the first supporting plate and mounted at the lower end of the light source, the photocell component comprises a side plate with a second supporting plate, the side plate is fixed at the inner lower end of the camera obscura, a steel disc slit on a cover plate connected with the side plate is mounted at the lower end of the collimating lens, a photocell is fixed on the second supporting plate, and the shutter is mounted between the light source component and the photocell component. The device meets the requirements on the curtain type shutter exposure uniformity detection.
Description
technical field [0001] The invention relates to the technical field of aerospace imaging, in particular to a curtain-type shutter exposure uniformity detection device. Background technique [0002] With the development of CCD devices, area array CCD devices have become an important direction of aerospace imaging media. Due to the characteristics of the area array CCD device itself, when it is used as an imaging medium, it must cooperate with a mechanical shutter to complete normal exposure imaging. [0003] At present, there are two kinds of mechanical shutters commonly used: central shutter and curtain shutter. In area array CCD cameras, curtain shutter is usually used. Due to the fast movement speed of the curtain slit of the curtain shutter and the wide range of the slit width, it is difficult to detect the exposure uniformity of the area array CCD camera. At present, a simple detection device is used for exposure uniformity detection, which uses the light emitted by a ...
