The invention relates to the technical field of photoelectronic imaging, and discloses an optical filter shifting device and imaging equipment including the optical filter shifting device. The optical filter shifting device comprises a base, a rotary table assembly placed in the base and capable of rotating, and several optical filters arranged in the rotary table assembly and rotating along with a rotary table. A window enabling extraneous light to penetrate through and capable of being aligned to the optical filters is arranged in the base, a first groove used for placing of the rotary table assembly is formed in the base, and the window is communicated with the first groove. Compared with the prior art, multiple optical filters can be placed in the rotary table assembly according to actual needs, the position of the window on the base is fixed, the rotary table assembly drives the optical filters to rotate through a rotating mode until the needed optical filters are aligned to the window on the base, namely, switching of the optical filters is achieved through the rotating mode, a switching process is easy to operate, and positioning of the optical filters is accurate.
Description
technical field [0001] The invention relates to the technical field of photoelectric imaging, in particular to a filter switching device capable of accurately switching a plurality of filters and an imaging device using the filter switching device. Background technique [0002] In imaging devices such as cameras, in order to satisfy better imaging in various complex environments, that is, for each different environment, the imaging device needs to filter the light entering it to remove some interference or unwanted light, Imaging equipment is equipped with a filter switching device that can filter light. For different environments, it can automatically switch to the required filter and perform light filtering. [0003] In the present technology, the optical filter switching device generally adopts the mode of magnetic attraction to switch the optical filter, that is, to use the effect of magnetic force to perform the optical filter switching operation, which has the followin...
