First Claim
1. A method of determining a source position of an incoming light source, comprising:
- a. translating a plurality of microlenses to a plurality of known lens positions;
b. detecting energy from the incoming light source through the plurality of microlenses on a corresponding plurality of opto devices;
c. determining an estimate of direction of the incoming light source relative to the opto devices based on the detected energy at each of the plurality of opto devices.

Abstract
A system and method for laser source detection. An exemplary embodiment of the system includes a first array of lenses, a second array of opto devices (including light sources and light detectors), and at least one processor. Energy from the light source may be detected at the array of opto devices having lenses at known positions, to allow the approximate location of the laser source to be determined. Upon determining the source, responsive action may be taken. If the incoming laser is from a friendly party, a friendly-party notification may be provided. If the incoming laser is from an enemy, reciprocal targeting or false reflections may be employed.
