Methods for detecting a time-of-flight include: emitting a light pulse toward a target; detecting a presence of light received at a light detector; obtaining a delay time between emitting the light pulse and detecting the presence of the light at the light detector; responsive to obtaining the delay time, (a) updating an overall intensity counter that counts a total number of delay times that have been obtained and (b) updating a delay time counter out of a plurality of different delay time counters, wherein each delay time counter counts a total number of delay times obtained that have a corresponding delay time value; and monitoring a threshold of each delay time counter to determine whether a threshold value is exceeded.

Illuminator modules having improved safety features are described. In some implementations, light to be emitted from a module is produced by a light source, and light reflected by an optical component disposed over the light source is detected by a photodetectors. A distribution of the reflected light detected by the photodetectors is monitored, and an optical output power of the light source is regulated if it is determined, based on the monitored distribution of light, that an unsafe level of light may be emitted from the module.
