摘要： A distance-measuring device includes a light-emitting/sensing controlling circuit, a light-emitting component, a light-sensing group, a background-calculating circuit, a frequency-adjusting circuit, and a distance-calculating circuit. The light-emitting component emits a detecting light to a measured object. The light-emitting/sensing controlling circuit controls the light-sensing group receiving and accumulating the energy of a reflective light generated by the measured object reflecting the detecting light, so that the distance-calculating circuit can calculate a measured distance between the measured object and the distance-measuring device according the accumulated energy of the light-sensing group. In addition, the distance-measuring device calculates the energy accumulated by the light-sensing group sensing the background light per unit time, by means of the background-calculating circuit. In this way, the effect of the background light is reduced so that the distance-measuring device can more correctly calculate the measured distance.
