Abstract
An optical system for collecting distance information within a field is provided. The optical system may include lenses for collecting photons from a field and may include lenses for distributing photons to a field. The optical system may include lenses that collimate photons passed by an aperture, optical filters that reject normally incident light outside of the operating wavelength, and pixels that detect incident photons. The optical system may further include illumination sources that output photons at an operating wavelength.
Claims10
An optical channel for receiving photons and detecting the photons comprising:
- a bulk imaging optic;
- an aperture layer located at an imaging plane of the bulk optic;
- a collimating lens layer behind the aperture layer and separated therefrom by a focal length of the collimating lens layer;
- an optical filter behind the collimating lens layer;
- and
- a pixel offset from the optical filter opposite the collimating lens layer, and responsive to photons incident on the pixel.
