摘要：A distance measuring instrument comprises: at least one light source (5); atleast one light detector (9); optics (23) to direct measuring light emitted from the at leastone light source towards an object (3) and to direct measuring light received back fromthe object to the at least one detector; a signal delay module (51); a first signal analyzer(42); and a variable gain amplifier (33). A distance measuring method comprises: emitting apulse of measuring light towards an object; receiving a pulse measuring light from theobject and generating a pulse signal corresponding to the pulse of measuring lightreceived from the object; delaying a first portion of the generated pulse signal for apredetermined time; generating an intensity signal indicative of an intensity of thegenerated pulse signal, while delaying the first portion of the generated pulse signal;amplifying the delayed first portion of the generated pulse signal using a gain dependenton the generated intensity signal; determining a value representing a distance based onthe amplified delayed first portion of the generated pulse signal.
