Sound light polarization spectrum camera

Abstract

The invention relates to a sound light polarization spectrum camera which is a system combining three optics detection technologies imaging, spectrum and polarization together. The sound light polarization spectrum camera can obtain the surface morphology information of an object to be measured and the polarization information and spectrum information of the reflected light of the object to be measured in visible light and near infrared wave band. The invention is characterized in that a polarization imaging technology and a spectrum imaging technology are combined; in the spectrum polarization image provided in the technology, the relevant polarization spectrum and image information of object reflection or diffusion light can be acquired; not only a rather high spatial resolution and spectrum resolution are possessed, but also the sharpness, contrast of the image and the detection distance are improved. The spectrum part employs a sound light modulation light splitting technology. The acousto-optic adjustable filter has characteristics such as small volume, light weight, all solid state, no mobile part, good anti-shock performance, strong adaptive capacity to environment and the like. Application fields of the invention comprises atmosphere detection, sea investigation, earth resource investigation, calamity prediction, medical science diagnosis, military object detection and identification, image understanding and the like.

Description

technical field [0001] The invention relates to an acousto-optic polarization spectrum camera, which can collect the polarization, spectrum and image data of the target to be measured in the visible or near-infrared band, and deduce the surface roughness, texture direction, surface orientation, surface conductivity, etc. of the target to be measured.
