US Patent:

20190086520, Mar 21, 2019

Filed:

Sep 19, 2017

Appl. No.:

15/708268

Inventors:

- Mayfield Heights OH, US
Mei Li - Wellesley MA, US

International Classification:

G01S 7/486
G01S 17/10

Abstract:

A time of flight sensor device is provided that is capable of generating accurate information relating to propagation time of emitted light pulses using a small number of measurements or data captures. By generating pulse time of flight information using a relatively small number of measurement cycles, object distance information can be generated more quickly, resulting in faster sensor response times. Embodiments of the time of flight sensor can also minimize or eliminate the adverse effects of ambient light on time of flight measurement. Moreover, some embodiments execute time of flight measurement techniques that can achieve high measurement precision even when using relatively long light pulses having irregular, non-rectangular shapes.
