| Abstract(in English) | Because of their low cost, light weight, low power consumption and durability, semiconductor lasers are ideal, for use as optical range finder light-sources. Their oscillation-frequency fluctuations generate the physical random numbers, which are used to measure distances. While normal range finders use modulation signals, such as sharp pulses, the method we devised employs semiconductor lasers' frequency noise, and a frequency to intensity converter, such as the rubidium absorption profile, to produce physical random numbers. This allowed us to construct an optical range finder that requires no additional modulation of the semiconductor laser, - has a range of up to 50 meters, and resolution of 0.06 meters. We also consider the resolving power of this method without changing its sampling rate. |
