DEVICE FOR TIMING LASER RANGE-FINDER Russian patent published in 2008 - IPC G01C3/08 

FIELD: measuring techniques.

SUBSTANCE: proposed device for timing a laser range-finder comprises a first differentiator and a zero-comparator, and a second differentiator, connected in series to the first differentiator with differentiation constant τ_d'. 0.3t_p<τ_d'<5t_p, where t_p is pulse duration at the input of the timing device.

EFFECT: provision for maximum accuracy of a laser range-finder in a wide range of measured ranges due to implementation of the zero intersection principle in the timing device.
