Abstract
For accurately detecting a desired laser signal without being affected by ambient noise light pulse, a laser signal receiving apparatus, which receives a light pulse transmitted from a laser transmitter, includes a light receiving section having a photo-electric converter for converting a light pulse into an electric pulse signal, a pulse-width detecting section for detecting a pulse-width of the pulse signal derived from the light receiving section and a controlling section having a counter port supplied with the pulse signal and a pulse-width detector port supplied with an output of the pulse-width detecting section, so as to count only the pulse signal having a predetermined pulse-width, based on an output of the pulse-width detecting section.
