Abstract
An imaging sensor comprising a substrate having a light sensitive region and an array of electrodes defining a plurality of pixels, wherein the imaging sensor further comprises a layer of an upconverter material, is provided. The sensor may be used in an imaging device capable of detecting light at wavelengths longer than 1064 nm. The imaging device may also simultaneously detect visible light.
Claims46
An imaging sensor comprising a substrate having a light sensitive region and an electrode array comprising a plurality of electrodes arranged on the light sensitive region to define a plurality of pixels, a layer of upconverter material distributed on the sensor, and a multiplier for multiplying charge accumulated in the electrode array.
An imaging sensor comprising a substrate having a light sensitive region and an electrode array comprising a plurality of electrodes arranged on the light sensitive region to define a plurality of pixels, and a layer of storage phosphor distributed on the sensor and acting as a upconverter material.
An imaging sensor comprising a substrate having a light sensitive region and an electrode array comprising a plurality of electrodes being arranged on the light sensitive region to define a plurality of pixels, and a layer of an upconverter material, the upconverter material being distributed on the sensor such that the amount of light entering the sensor is controlled.
An imaging sensor comprising a substrate having a light sensitive region and an electrode array comprising a plurality of electrodes and arranged on the light sensitive region to define a plurality of pixels, and a layer of an upconverter material distributed on a face of the light sensitive region opposite the face of the light sensitive region where light entering the sensor is incident.
An imaging sensor comprising a substrate having a light sensitive region and an electrode array comprising a plurality of electrodes being arranged on the light sensitive region to define a plurality of pixels, and a layer of an upconverter material, the upconverter material being distributed on the sensor such that a portion of the light entering the sensor is incident on the upconverter material and a portion of the light entering the sensor is incident on the light sensitive region.
