Abstract
Per-pixel performance is improved in a combined visible and ultraviolet image sensor array such as for a hyperspectral camera. In one example, an array of photodetectors is formed on a silicon substrate. A subset of the photodetectors are improved to improve sensitivity to ultraviolet light, and the photodetector array is finished to form an image sensor.
Claims10
-11. (canceled)
An image sensor comprising:
- a silicon substrate;
- a first set of photodetectors on the silicon substrate that have a thin layer over an active area to improve sensitivity to ultraviolet light;
- a second set of photodetectors on the silicon substrate, that do not have the thin layer;
- and
- an optical system to direct visible and infrared light to the first and the second sets of photodetectors.
2 more elements
A portable computing system comprising:
- a processor;
- a communications chip coupled to the processor to send and receive images;
- and
- an image sensor coupled to the processor having a silicon substrate, a first set of photodetectors on the silicon substrate that have a thin layer over an active area to improve sensitivity to ultraviolet light, a second set of photodetectors on the silicon substrate, that do not have the thin layer, and an optical system to direct visible and infrared light to the first and the second sets of photodetectors.
