Abstract: A sensor (233) includes a first image pixel array (201) including first image pixels (P1, P2, P3Pn, 370) and a second image pixel array (251) including second image pixels (380). A polarization layer (355) is disposed between the first image pixels (P1, P2, P3Pn, 370) and the second image pixels (380). Scene light (339) incident upon the second image pixels (380) propagates through the first image pixels (P1, P2, P3Pn, 370) and the polarization layer (355) to reach the second image pixels (380).

Abstract: A system for collecting data for training a computer vision model for shape estimation includes: an imaging system configured to capture one or more images; and a processing system including a processor and memory storing instructions that, when executed by the processor, cause the processor to: receive one or more input images from the imaging system; estimate a pose of an object depicted in the one or more images; render a shape estimate from a 3-D model of the object posed in accordance with the pose of the object; and generate a data point of a training dataset, the data point including one or more images based on the one or more input images and a label corresponding to the one or more images, the label including the shape estimate.

Abstract: An optical system includes a display, a reflective polarizer, and a glare trap. The glare trap includes a plurality of slats having a length L and a width W, L/W ≥ 10. The slats form a plurality of elongated slots therebetween substantially filled with air. The reflective polarizer has an average optical reflectance of at least 40% for a first polarization state and an average optical transmittance of at least 40% for an orthogonal second polarization state. For each of the first and second polarization states, the glare trap has an average specular optical transmittance of between about 20% to about 80% and an average total optical reflectance of less than about 20%. For at least one wavelength in the visible wavelength range, an optical transmittance of the glare trap includes a first transmittance peak at a first peak angle with a corresponding FWHM of less than about 30 degrees.
