Abstract
A distance measuring device and a method for determining a distance are provided. The method includes: illuminating an object with a sequence of the light pulses, capturing one arriving light pulse corresponding to an intensity Ie,l within a first integration gate, and outputting a signal value U1, capturing another arriving light pulse corresponding to the intensity Ie,l within a second integration gate, and outputting a signal value U2, capturing one arriving light pulse corresponding to an intensity Ie,h within the first integration gate and outputting a signal value U3, capturing the other arriving light pulse corresponding to the intensity Ie,h within the second integration gate and outputting a signal value U4, and calculating the distance between the distance measuring device and the object based on U1, U2, U3, and U4.
