Title:
SNAPSHOT-TYPE POLARIZED HYPER-SPECTRAL CAMERA AND IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/004899
Kind Code:
A1
Abstract:
A snapshot-type polarized hyper-spectral camera and an imaging method. The camera comprises polarizers (11), an image sensor (12), and a spectra filter (13). The spectra filter (13) is located on the image sensor (12). The polarizers (11) are located on one side of the image sensor (12). The method comprises: shielding and transmitting incident light by means of polarizers (11), so as to obtain light signals having different polarizing angles (101); receiving, by means of an image sensor (12), the light signals having different polarizing angles, which are obtained by the polarizers (11), and converting the light signals having different polarizing angles into electric signals (102); and receiving, by means of a spectra filter (13), the electric signals converted by the image sensor (12), and filtering the electric signals, so as to obtain pre-set wavelength high-frequency electric signals (103). By integrating a spectra filter (13) on a tiled pixel array of a sensor, a quick change scenario can be imaged; and meanwhile, by sticking a plurality of polarizers (11) into each specific wavelength channel, more exquisite imaging is realized.
