Abstract

The invention discloses a light filter switching device for a polarization imaging camera. The light filter switching device comprises a rotating shaft and a rotating plate. The rotating shaft is connected with a drive device. The center of the rotating plate is fixedly connected with the rotating shaft. The rotating plate is provided with a plurality of light filter holes in the peripheral direction. Light filters are fixed on the light filter holes. Diaphragms are arranged on the surfaces of the light filters. The light filter switching device can spin the multiple light filters, the light filters can be switched at any time according to the different testing requirements, the testing effect can be effectively improved, and the testing precision is improved. The light filter switching device is simple in structure, convenient to install and use and high in applicability.

Description

[0001] technical field [0002] The invention relates to an auxiliary device for optical filters, in particular to an optical filter switching device for a polarization imaging camera. Background technique [0003] Polarization imaging or Stokes polarization imaging technology is a new image detection technology developed in recent years. Compared with the traditional light intensity image detection technology, it can obtain the polarization intensity, Parameters such as degree of polarization, polarization angle, and polarization ellipticity greatly increase the amount of information of the detected target. Based on these advantages, polarization imaging technology has important application value in the fields of medicine, industry and national defense. [0004] By adopting a long rear working distance objective lens composed of a front negative lens group and a rear positive lens group, the distance between the objective lens and the image sensor can be effectively increa...
