dc.description.abstract | Disclosed is a high resolution time-of-flight distance measurement device based on a femtosecond laser, including a femtosecond laser light source, a polarization beam splitter, a balanced optical cross-correlator in which second harmonic pulses are generated using reference light and measurement light, wherein the second harmonic pulse that was primarily generated is incident on a first photodetector and the second harmonic pulse that was secondarily generated is incident on a second photodetector, so that a difference in intensity of the second harmonic pulses is output, thus resolving the time interval of the pulse laser, a controller for controlling the repetition rate of the femtosecond laser, and a converter for measuring the repetition rate of the femtosecond laser controlled so that the pulses uniformly overlap by means of the controller, using a frequency counter traceable to a time/frequency standard, so that a measured value is converted into distance information. | - |
