20110157579 | Distance-measuring device with increased signal-to-noise ratio and method thereof - A method of increasing signal-to-noise ratio of a distance-measuring device includes a light-emitting component emitting a detecting light to a measured object during an emitting period for generating a reflected light, a delay period after the light-emitting component emitting the detecting light, a light-sensing component sensing the energy of the reflected light to generate a light-sensing signal, and obtaining a measured distance between the distance-measuring device and the measured object according to the energy of the detecting light and the light-sensing signal. Since the measured distance is longer than a predetermined shortest measured distance, the method can accordingly calculate a proper delay period for ensuring that the reflected light reaches the light-sensing component after the delay period. In this way, the light-sensing component does not sense the background light during the delay period, so that the signal-to-noise ratio of the light-sensing signal is improved. | 06-30-2011 |
