Abstract
Methods and apparatus for receiving a return laser pulse at a detector system having pixels in a pixel array and analyzing a response of the pixels in the pixel array including comparing the response to at least one threshold corresponding to decay of photonic energy of the laser pulse over distance and target reflectivity, wherein the at least one threshold comprises a first threshold corresponding to a low trigger for a pulse generated by a first type of laser and a second threshold corresponding to a high trigger for the pulse generated by the first type of laser. Embodiments can further include generating an alert signal based on the response of the pixels in the pixel array.
Claims22
A method, comprising:
- receiving a return laser pulse at a detector system having pixels in a pixel array;
- analyzing a response of the pixels in the pixel array including comparing the response to at least one threshold corresponding to decay of photonic energy of the laser pulse over distance and target reflectivity, wherein the at least one threshold comprises a first threshold corresponding to a low trigger for a pulse generated by a first type of laser and a second threshold corresponding to a high trigger for the pulse generated by the first type of laser;
- and
- generating an alert signal based on the response of the pixels in the pixel array.
A detector system, comprising
- a detector to receive a return laser pulse, wherein the detector comprises pixels in a pixel array;
- a first module configured to analyze a response of the pixels in the pixel array including comparing the response to at least one threshold corresponding to decay of photonic energy of the laser pulse over distance and target reflectivity, wherein the at least one threshold comprises a first threshold corresponding to a low trigger for a pulse generated by a first type of laser and a second threshold corresponding to a high trigger for the pulse generated by the first type of laser;
- and
- an alert signal configured to generate an alert based on the response of the pixels in the pixel array.
