Abstract: A method includes counting a first set of photons having a time-of-flight that falls within a first time range and being detected during a first time period, determining a second time range based on the first set of photons, the second time range being smaller than the first time range, counting a second set of photons having a time-of-flight that fall within the second time range and being detected during a second time period, and determining a third time range based on the second set of photons, the third time range being smaller than the second time range.

Abstract: A method for managing a dynamic range of an optical detection device illuminated by a modulated optical radiation, the method including: generating a detection signal from the modulated optical radiation; generating, based on the detection signal, a histogram including a plurality of histogram classes; comparing a chosen maximum value and a value of each histogram class of the plurality of histogram classes; and stopping a generation of the histogram in response to a determination that the value of any one of the plurality of histogram classes is equal to the maximum value.
