Abstract
An imaging system may include an image sensor, a lens, and layers with reflective properties, such as an infrared cut-off filter, between the lens and the image sensor. The lens may focus light from an object in a scene onto the image sensor. Some of the light directed onto the image sensor may form a first image on the image sensor. Other portions of the light directed onto the image sensor may reflect off of the image sensor and back towards the layers with reflective properties. These layers may reflect the light back onto the image sensor, forming a second image that is shifted relative to the first image. Depth mapping circuitry may compare the first and second images to determine the distance between the imaging system and the object in the scene.
