Patent number: 10960465Abstract: A method and an apparatus pertaining to recycling and reuse of unwanted light in additive manufacturing can multiplex multiple beams of light including at least one or more beams of light from one or more light sources. The multiple beams of light may be reshaped and blended to provide a first beam of light. A spatial polarization pattern may be applied on the first beam of light to provide a second beam of light. Polarization states of the second beam of light may be split to reflect a third beam of light, which may be reshaped into a fourth beam of light. The fourth beam of light may be introduced as one of the multiple beams of light to result in a fifth beam of light.Type: GrantFiled: October 28, 2016Date of Patent: March 30, 2021Assignee: SEURAT TECHNOLOGIES, INC.Inventors: James A.

Patent number: 10824052Abstract: Various embodiments described herein relates to a lens cap, adapted to be mechanically engaged over a lens assembly of an optical projector. The lens cap, as described herein, is adapted for vignetting a light pattern projected by the optical projector. The lens cap includes a front surface and a back surface, where on at least a portion of the front surface, an elliptically shaped aperture is defined. In this aspect, the elliptically shaped aperture is chamfered towards its peripheral ends, as the elliptically shaped aperture extends out from the back surface of the lens cap towards the front surface of lens cap. Also, the elliptically shaped aperture is defined on the lens cap such that, a center axis of the aperture is offset to a central axis of the lens cap, so as to match an offset at which the light pattern is projected by the optical projector.Type: GrantFiled: August 28, 2018Date of Patent: November 3, 2020Assignee: Hand Held Products, Inc.Inventor: Chen Feng

Patent number: 10795169Abstract: An illuminator optical system combines, homogenizes, and shapes light spatially and angularly from one or more high power fiber coupled lasers. It may include a multichannel fiber cable, collimation and beam shaping optics, a multiple lens array (e.g., fly's eye lens array), and an objective lens. The multichannel fiber collects the light from the high power fiber coupled lasers and produces an aligned array of one or more optical fibers at the output of the cable. The light output from the cable is collimated and relayed to a multiple lens array that spatially divides and shapes the light into an array of beams. The objective lens homogenizes the light by collimating and overlapping the beams into a uniform top hat irradiance distribution in at least one dimension, resulting in the illumination pattern having the required spatial size and desired angular distribution at the illumination plane.Type: GrantFiled: December 10, 2019Date of Patent: October 6, 2020Assignee: Palo Alto Research Center IncorporatedInventors: Patrick Y.
