Abstract
An optical information collection system includes a neuromorphic sensor to collect optical information from a scene in response to change in photon flux detected at a plurality of photoreceptors of the neuromorphic sensor. A sensor stimulator stimulates a subset of the plurality of photoreceptors according to an eye movement pattern in response to a control command. A controller generates the control command that includes instructions to execute the eye movement pattern.
Claims20
An optical information collection system, comprising:
- a neuromorphic sensor to collect optical information from a scene in response to change in photon flux detected at a plurality of photoreceptors of the neuromorphic sensor;
- a sensor stimulator to stimulate a subset of the plurality of photoreceptors according to a fixational eye movement model that defines an eye movement pattern in response to a control command, wherein the fixational eye-movement model includes a first parameter that describes a first position for the sensor stimulator and includes a second parameter that describes a movement of the sensor stimulator to stimulate the plurality of photoreceptors;
- and
- a controller to generate the control command that includes instructions to execute the eye movement model.

A device, comprising:
- a housing that includes an optical lens to receive optical information from a scene;
- a neuromorphic sensor within the housing to collect optical information from the scene via the optical lens;
- a sensor stimulator to stimulate the neuromorphic sensor according to an eye-movement pattern in response to a control command;
- and
- a controller in the housing to generate the control command to the sensor stimulator to cause movement of the sensor stimulator according to the eye-movement pattern to approximate movements of a human eye and enable collection of the optical information from the scene, the eye-movement pattern includes a first parameter that describes a first position for the sensor stimulator and includes a second parameter that describes movement of the sensor stimulator along a specified distance and direction away from the first position.
