초록 ▼

A laser speed detector is described which includes a laser rangefinder which determines the time-of-flight of an infrared laser pulse to a target and a microprocessor-based microcontroller. The device is small enough to be easily hand-held, and includes a trigger and a sighting scope for a user to visually select a target and to trigger operation of the device upon the selected target. The laser rangefinder includes self-calibrating interpolation circuitry, a digital logic-operated gate for reflected laser pulses in which both the “opening”and the “closing”of the gate can be selectably set by the microcontroller, and dual collimation of the outgoing laser pulse such that a minor portion of the outgoing laser pulse is sent to means for producing a timing reference signal.

대표청구항 ▼

A laser speed detector, comprising: a housing having dimensions suitable for being hand-held during operation; a power source positioned Within said housing and providing a high voltage output and a low voltage output as required to other components; a laser rangefinder system disposed within said housing, including a laser pulse generator and laser light detection means, and constructed to determine the time-of-flight of a laser pulse to a target and back to said light detection means; a sighting scope attached to said housing and operably associated with said laser rangefinder such that when a user views a selected target through said sighting scope, said laser pulse generator and said light detector are simultaneously aimed at said selected target; a trigger mounted to said housing to be operable by a user to trigger operation of said speed detector when said laser pulse generator is aimed at said selected target; and control means including a microcontroller having memory means for storing instructions and data, said microcontroller being communicatively interconnected to said Dower source and said laser rangefinder and said control means being configured to: calculate a plurality of distances to said target from said flight times and the speed of light, each corresponding to a different successive ones of a series of laser pulses; and calculate a velocity of said target relative to said observer based on said distances and the elapsed time between the individual said pulses corresponding to said distances.
