摘要： A laser surveying instrument comprising a light source unit having two or more light emission sources for emitting pulsed distance measuring lights with different wavelengths, a light projecting unit for projecting the pulsed distance measuring lights with the two or more wavelengths on an optical axis, and a deflection member provided on the optical axis, is disclosed. The deflection member has two or more reflection surfaces which reflect each wavelength of the pulsed distance measuring lights independently, thereby dividing the pulsed distance measuring lights for every wavelength, and deflecting each of the distance measuring lights toward an object to be measured. The instrument comprises a single photodetection element for receiving reflected distance measuring lights from the object to be measured. In the laser surveying instrument, a measurement of distance is performed for every pulsed distance measuring light based on a photodetection signal produced by the photodetection element.
