Description

Technical Field

[0001] The utility model relates to the field of shutters, and more particularly to a thermal imaging shutter. Background Art

[0002] Thermal imaging technology is a technology that uses infrared radiation heat to detect and image objects, and the shutter is an important component of a thermal imaging camera. The shutter controls the exposure time of the camera by controlling the time when light enters the camera, thereby capturing and imaging the infrared radiation of the object.

[0003] When opening and closing, existing shutters mostly use a swing shaft and two leaves of a split structure to complete the opening and closing of the shutter. However, the swing shaft collides with the leaves when driving them to open and close, which makes the leaves prone to noise during the opening and closing process and also generates vibration, thereby affecting the thermal imaging camera's capture and imaging of the object's infrared radiation.
