Publication number: 20240137656Abstract: An optical system includes a spatial encoding arrangement for generating spatially encoded light with an initial spatial distribution; a coded aperture defining a mask pattern based on the initial spatial distribution of the spatially encoded light; and—an image sensor. The spatial encoding arrangement—directs the spatially encoded light onto the object, and the object reflects at least a portion of the spatially encoded light to form reflected light. The reflected light is directed through the coded aperture to form spatially decoded light. The spatially decoded light is directed onto the image sensor to form an image thereon, and the image sensor detects the image. The spatial encoding arrangement includes optical emitters spatially arranged, defining the initial spatial pattern of the spatially encoded light. The mask pattern is the inverse of the initial spatial pattern of the spatially encoded light defined by the spatial arrangement of the optical emitters.Type: ApplicationFiled: February 7, 2022Publication date: April 25, 2024Inventors: Francesco Paolo D'ALEO, Markus ROSSI, Jens GEIGER
