Beschreibung
Zusammenfassung:	The utility model provides an optical distance measuring device capable of reducing or eliminating a stacking effect in a DToF distance measuring method. The optical distance measuring device comprises a light source used for emitting pulse type measuring light; the sensor module comprises an SPAD array, the SPAD array comprises a first group of SPAD and a second group of SPAD, the first group of SPAD is not provided with a diaphragm, the second group of SPAD is provided with a first diaphragm used for reducing the light flux, and the sensor module outputs a photon detection value corresponding to the number of photons received by each group of SPAD based on the measurement light received by each SPAD; the detection circuit is connected to the sensor module and is used for determining the distance between the to-be-detected object and the distance measuring device based on DDoF by using the photon detection value, and the distance measuring device is used for measuring the distance between the to-be-detected
