Sony patents camera system that measures light polarization by color

Sony has filed a patent for a device that combines two types of cameras to analyze light. One camera captures images across different wavelengths, while the other uses a filter to measure how much the light is polarized. The system processes these signals to create data showing how polarization changes depending on the color of the light.

Why it mattersThis technology could improve how machines analyze materials or surfaces by providing detailed data on how light interacts with them.

In the filing’s own words

It is desirable to provide information associated with information regarding polarization for an application and the like with machine learning. An information generation apparatus includes a spectroscopic information processing unit that generates polarization degree information that indicates wavelength dependency of a polarization degree from first spectroscopic information that is an imaging signal for each of a plurality of wavelength bands from a first spectroscopic camera and second spectroscopic information that is an imaging signal of the plurality of wavelength bands of light received by a second spectroscopic camera via a polarizing filter.

What exactly they claim (claim 1)

1. An information generation apparatus comprising a spectroscopic information processing unit that generates polarization degree information that indicates wavelength dependency of a polarization degree from first spectroscopic information that is an imaging signal for each of a plurality of wavelength bands from a first spectroscopic camera and second spectroscopic information that is an imaging signal of the plurality of wavelength bands of light received by a second spectroscopic camera via a polarizing filter.
