Abstract
A live-fire simulation system uses a position sensitive detector (PSD) in a weapon-mounted sensor to intercept emitted light from target emitters spatially distributed about a target. Each target emitter is modulated with a unique frequency. The system can thus not only determine the points of interception on the PSD but also determine which emitter caused which interception by using a frequency analysis.
Claims22
A sensor, comprising:
- a detector comprising a lateral effect photodiode comprising a single contiguous active area adapted to receive uniquely modulated light from each of at least three target emitters at corresponding positions on the active area and to generate output signals based on the received light;
- and
- a processor configured to receive the output signals from the detector and to calculate pointing angles from the detector to the target emitters from the output signals.
A method of calculating an aim point, comprising:
- providing a target having at least three spatially-distributed target emitters, each target emitter emitting light at a different modulated frequency;
- receiving the emitted light from the emitters at corresponding locations on a single contiguous active area of a lateral effect photodiode, wherein a detector comprises the photodiode, wherein the detector is associated with a weapon;
- generating a plurality of output signals based on the receiving;
- and
- calculating pointing angles from the detector to the emitters using the output signals.
