In an embodiment, the tracker laser rangefinder includes a laser source arranged to generate and emit a laser pulse at a first time in response to a laser trigger signal; a fast-scan mirror arranged to deflect and steer the laser pulse to an object in a scan plane; a sensor arranged to receive a reflection of the laser pulse from the object at a second time and output a return pulse detection signal; and a controller arranged to receive the return pulse detection signal and determine a first angle, a second angle and a range to the object. The first angle and the second angle can be based on a position of the fast-scan mirror. The range of the object can be calculated based on a period of time comprising the first time as a start time and the second time as a stop time. | 2022-06-30 |
20220206123 | LIGHT SCANNING DEVICE AND DISTANCE MEASURING DEVICE - A light scanning device includes a light emitter configured to emit light; an optical scanner configured to cause the light to scan; a light receiver configured to receive returning light as scanning light from the optical scanner being reflected or scattered on an object; and an optical scanning controller including processing circuitry configured to control the optical scanner. The optical scanner includes a rotating polyhedron configured to include a plurality of reflective surfaces, to cause the light to scan around a first axis by reflecting the light on a reflective surface while rotating around the first axis; a supporter configured to support the rotating polyhedron; and a rotating mechanism configured to rotate the supporter around a second axis that crosses the first axis, to cause the light reflected on the reflective surface to scan around the second axis. | 2022-06-30 |
