Abstract
A distance measurement instrument 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 along a transmit path at an emission time and a return light signal is received by a receiver unit at a receive time along a receive path. 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 at a deflection angle relative to an optical axis 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 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 based on at least the emission time and the receive time.
