    Abstract: An imaging system includes a transmissive diffraction mask (TDM), a pixel array, and a processor. The TDM includes a first and a second diffraction grating configured to diffract light received from a scene to generate first diffracted light encoding information about an angle of incidence (AOI) of the received light and second diffracted light encoding information about the AOI and a state of polarization (SOP) of the received light, respectively. The pixel array includes a first and a second set of pixels configured to detect the first and second diffracted light and generate therefrom a corresponding first and second set of pixel responses, respectively. The processor is configured to determine, from the first set of pixel responses, AOI data conveying the AOI of the received light, and determine, from the second set of pixel responses and the AOI data, polarization data conveying the SOP of the received light.

  • Patent number: 11865768
    Abstract: Methods and systems for forming objects through photo-curing of a liquid resin in a tank by selective exposure (through a mask) to radiation, in which during printing operations the liquid resin in the tank is displaced relative to the build area along an axis orthogonal to that along which the object is extracted from the liquid resin in the tank. A volume of the photo-curing liquid resin may be cycled through a cooling arrangement by being extracted from the tank, cooled, and then reintroduced into the tank as printing of the object is taking place. The mask is preferably one in which charged colorant particles are dispersed in an optically transparent fluid within a plurality of bi-state cells.
