Abstract: A system and method for determination of origin displacement for a laser rangefinding instrument which comprises laser transmitting and receiving sections coupled to a processor section. The processor section is configured to calculate ranges from the instrument to first and second target coordinates and to compensate for displacement between disparate first and second origin points in order to determine a distance between these target coordinates.

Abstract: An optical baffle and combination with a laser sensor of especial applicability in attenuating off-axis laser light in the use of a laser sensor for determining the height of a liquid level or distance to a surface detectable through a pipe.

Abstract: Disclosed herein is a handheld speed gun incorporating automatic number plate recognition (ANPR) functionality. As the image size of a vehicle license plate varies depending on its distance from the speed gun, in the present invention the distance to the target vehicle is known through the functionality of the laser sensor so the size of the pixels for the number plate can be estimated. Since the image of the number plate may be tilted in a handheld device, the present invention compensates for this by use of the instrument's tilt sensor or through other compensation by use of the image itself.

Abstract: A system and method for a rangefinding instrument incorporating pulse and continuous wave signal generating and processing techniques for increased distance measurement accuracy. The use of the former technique effectively solves the ambiguity issues inherent in the latter while allowing for relatively simple circuit implementations. Thus, a potentially more accurate phase-based distance measurement technique can be utilized which is also completely independent of the maximum range to the target.
