Publication number: 20240210246Abstract: An attachment for an intensity-only sensor in an imaging device includes a polarization-sensitive diffraction grating. The polarization-sensitive diffraction grating is configured to receive incident light from a scene, and to modify the incident light to simultaneously produce a plurality of non-overlapping images of the scene. each of a different diffraction order, on the intensity-only sensor to facilitate full-Stokes imaging polarimetry. The attachment includes a first adjustment mechanism configured to control at least one of: vignetting of the plurality of non-overlapping images on the intensity-only sensor, or an object distance of the imaging device.Type: ApplicationFiled: July 22, 2022Publication date: June 27, 2024Applicant: PRESIDENT AND FELLOWS OF HARVARD COLLEGEInventors: Noah A. RUBIN, Paul CHEVALIER, Federico CAPASSO
