A laser-based rangefinding instrument for, inter alia, golfing or hunting activities having an unique ergonomic design and an external multi-function switch for controlling display brightness, selectable display of differing distance units and a slope selection switch for enabling display of line of sight distance or angle of slope and 'Compensated Golf Distance' slope distance to a target.

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.

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.

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.

A backlight system for a display device which comprises a light emitting diode comprising an encapsulating lens and an aspheric lens interposed between the light emitting diode and the display device. The backlight system provides a luminance of substantially 100K nits at a cone angle of substantially 12&#xb0; and is of particular utility in conjunction with laser-based range and speed measurement instruments.

A technique for a pulse/phase based laser rangefinding instrument utilizing a single photodiode in conjunction with separate pulse and phase receiver circuits. The photodiode receives phase and pulse ranging signals and a capacitor coupled to the photodiode and is operative to provide current through the photodiode to a transimpedance amplifier in a pulse mode of operation and from the photodiode through a tuned circuit to a narrow band amplifier in a phase mode of operation.

A system and method for superimposing a virtual aiming mechanism with a projected system beam in a compact laser-based rangefinding instrument such as a laser-based tape measure which employs a laser rangefinding system beam and visible light beam to enable a user to merely pick up the instrument and, if the visible beam can be seen, merely aim the device without sighting by placing the resultant visible light dot on the target itself. Alternatively, if the beam cannot be seen, the user can sight through the instrument viewing aperture and see a virtual visible dot and superimpose it upon his view of the target.

A laser sensor module array for vehicle identification, speed monitoring and traffic safety applications. Each of the laser sensor modules comprise a laser signal transmitting and receiving port with the array comprising a basic row of N laser sensor modules, wherein N is greater than 1 and wherein each of the N laser sensor modules in the basic row is displaced at an acute angle with respect to adjacent ones of the laser sensor modules. An additional row of N laser sensor modules may adjoin the basic row of N laser sensor modules in a parallel or acute angular relationship to corresponding ones in the basic row.
