Method for operating a geodetic instrument, and related geodetic instrument

A method for operating a geodetic instrument comprising an optical source for assisting a user in aiming at a target in a scene and an imaging device, wherein the imaging device and the optical source share a common optical channel within the geodetic instrument, said method comprising:

• causing emission, by the optical source, of optical pulses towards the target;
• causing capture, by the imaging device, of images of the scene using a frame sequence, wherein a frame of said frame sequence includes an exposure time during which the imaging device is exposed to light from the scene, and wherein the frame sequence comprises a first subset of frames;
• synchronizing emission of the optical pulses to the frame sequence for obtaining data from images in which the optical pulses are absent, wherein the synchronizing comprises causing the optical source to be in a non-operating state during the exposure time of each frame of the first subset;
• processing data pertaining only to each frame of the first subset of frames;
• and
• causing the processed data pertaining only to each frame of the first subset of frames to be displayed as frames on a display.
