Rotation slot closure for digital camera e.g. shed camera, for digitization of e.g. archived document, has rotation disk made from carbon-reinforced composite material, where lens, image sensor and drive are modularly fastened to housing

摘要

The closure (10) has a rotation disk (11) projecting into an optical path between a lens (15) and an image sensor (16). Sector-shaped closure windows (12, 13) are formed in the disk, where the disk is rotated around a rotational axis by an electromotive drive (14). The disk is made from carbon-reinforced composite material and arranged in an exchangeable and light-proof rotation disk housing, where the lens, image sensor and the drive are modularly fastened to the housing. The drive is connected with a control unit, where the disk has diameter of 22.3 cm.
