    Abstract: A distance measurement instrument (400) and a method of operating a distance measurement instrument are disclosed. According to some embodiments, a transmit light signal is transmitted by a transmitter unit (406) along a transmit path (408) at an emission time and a return light signal is received by a receiver unit (407) at a receive time along a receive path (440). The return light signal is converted to a return electrical signal. At least one of the transmit path and the receive path is deflected by a deflection module (415) at a deflection angle relative to an optical axis (430) of the instrument. A time-dependent attenuation function is selected based on information relative to the deflection angle and attenuation is applied by an attenuator (480, 490) to at least one of the return light signal and the return electrical signal according to the selected time-dependent function. A measured distance may be determined by a processor unit (470) based on at least the emission time and the receive time.

    Abstract: The invention discloses the laser transponder system for disrupting speed and/or distance measuring LIDARs. The system consists of at least two laser transponders 101, 102, a microcontroller 103 and a user interface 104. The microcontroller 103 is connected to both laser transponders 101, 102, and to the user interface 104. Microcontroller 103 is analysing input from laser transponders 101, 102, and is determining their output. In case an advanced speed measuring LIDAR signal is detected the microcontroller 103 configures first laser transponder 101 as a transmitting only unit 101B and second laser transponder 102 as a receiving only unit 102B. Transmissions emanating from the transmitting only unit 101B are not received by the receiving only unit 102B. Disrupting signal periods are selected by the microcontroller 103 algorithm from its pre-stored database according to a detected LIDAR signal. Novelties of the invention are that the disrupting signal is transmitted simultaneously with synchronizing a disruption timer for the next period of a disrupting signal and that multiple disruption signal periods are timed in parallel on a given synchronization event. That way all speed measuring pulses of a LIDAR signal are disrupted even in the case of an advanced speed measuring LIDAR with a random pulse repetition rate. An additional novelty of the invention is that the laser transponders 101, 102, have a laser receiver with an adjustable gain controlled by the microcontroller 103, and that the microcontroller 103 algorithm discovers a maximum level of receiving only transponder 102B receiver sensitivity on which there is no echo triggering on transmissions emanating from the transmitting only transponder 101B.

    Abstract: An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There is a variable probability of a photon detection on the receiver, and a controller (370, 380, 390; 365, 470, 475, 380, 390; 570, 580, 590, 390) controls the photon detection probability of the receiver, based on a light level. By controlling the detection probability according to a light level, the receiver can have an increased dynamic range, and without the expense of using optical components. This can apply even while detecting very weak signals since the receiver can still be in a photon counting mode while the detection probability is controlled. The light level can be indicated by an output of the receiver itself, or by another detector external to the receiver.

    Abstract: The present invention relates to a range determination apparatus, in particular to a laser range finding apparatus. Presently available range finders usually provide a read out of the range to a single target and are unable to distinguish between multiple targets. Either the largest signal or the signal of the target closest to the range finder will generally be the one displayed. The present invention provides a display of range to multiple targets and also a display of the relative strength of each of the multiple target signal returns. This enables an operator to distinguish between targets in his field of view and locate the desired target and the range thereto. The display is preferably histogrammatic.
