发明名称 Apparatus and a method for measuring distance using a laser beam
摘要 A laser distance measuring apparatus which measures a turnaround time after emitting a laser beam outputted from a laser diode to a target until receiving the laser beam reflected by the target by a light receiving module via a band-pass filter to calculate a distance to the target, includes temperature control module for adjusting a temperature of the laser diode; level detecting module for detecting a level of the reflected laser beam received via the band-pass filter; main control module for outputting a temperature control signal to the temperature control module so that the level is kept in a predetermined range.
