Abstract

The invention discloses a multichannel combined optical filter wheel. A mode of combining a plurality of optical filter wheels is adopted in the scheme, the mature high-precision gear transmission technology is used for realizing the automatic orderly rotation of the plurality of optical filter wheels, the automation degree is high, and the transmission precision is good; furthermore, the structure of the device can be designed according to the required number of the optical filter wheel, the integral volume is optimized, the structure is compact, and the combined optical filter wheel can be placed in front of a focusing face of a multispectral camera, thereby realizing the multi-channel multi-wave spectral data acquisition.

Description

technical field [0001] The invention relates to the technical field of multi-spectral camera design, in particular to a multi-channel combined filter wheel. Background technique [0002] The filter wheel type multispectral camera is to add a filter wheel in the photographic optical path as a spectroscopic element, install a plurality of filters with different transmission wavelengths on the rotating wheel, and split the light by rotating the filter wheel, and according to The spectral response of the system is used to set the appropriate exposure time, and multiple spectral channel data of the same target can be obtained. By combining the above data in order of wavelength, the two-dimensional image information of the target and the spectral image including one-dimensional spectral information can be obtained. Data cubes have a wide range of applications in target recognition, remote sensing monitoring, and surveying and mapping. [0003] The mechanical structure design of t...
