Abstract
A multifunctional detector for emitting and receiving optical signals in order to determine the presence, location, and range movement of a player within a field of regard is disclosed. The detector generally includes a laser module operable for emitting an optical signal; an optional fiber optical delay line; a microcontroller/processor; a faceted scanning mirror pattern having multiple facets with each facet being tilted downward to allow for unique depressions for reflecting and scattering optical signals emitted by the laser module; a spinner/motor for driving and rotating the faceted mirror pattern; an optional combiner for separating emitted optical signals from the laser module or combining reflected optical signals from an reflective source; and a transceiver with an integrated APD receiver for receiving reflected optical signals combined from the combiner and transmitting reflected optical signal data to a central controller or other players. A method of using the detector is also disclosed.
