FIELD: instrument engineering.
SUBSTANCE: laser device for measurement of natural and artificial objects unstraight arrangement includes sequentially arranged laser, referent beam forming device and at least two photoelectric marks. The difference is that photoelectric mark contains mirror installed at an angle of 45° to referent direction and partially deflecting referent beam, light-diffusing element, lens and coordinate-sensitive optical detector. Note that light-diffusing element is installed between partially deflecting mirror and lens after which there is coordinate-sensitive optical detector.
EFFECT: improvement of invention accuracy.
