摘要： A laser driver (4) causes a semiconductor laser (1) to operate such that a first oscillation period of monotonically increasing the oscillation wavelength and a second oscillation period of monotonically decreasing the oscillation wavelength alternately exist. A photodiode (2) converts laser light emitted from the semiconductor laser (1) and return light from a measurement target (12) into electrical signals. A counting unit (13) counts the number of interference waveform components obtained from an output signal from the photodiode (2) in each of the first oscillation period and the second oscillation period. A computing device (9) calculates the distance to the measurement target (12) and the velocity of the measurement target (12) from a shortest Lasing wavelength and a longest Lasing wavelength in a period during which the counting unit (13) counts the number of interference waveform components and the counting result obtained by the counting unit (13). This makes it possible to measure the distance to the moving measurement target (12) and the velocity of the measurement target (12).

摘要： The frequency signal is divided into at least two frequency ranges corresponding to two main components of the frequency signal. Each frequency signal in the two ranges is subjected to separate Fourier transformation corresponding to respective complex time signals. The second time signal is divided by the first time signal by complex division to produce a third time signal. The latter is Fourier transformed to produce a processed frequency signal. Independent claims are also included for: (a) The use of the method to evaluate distance measurements using pulsed electromagnetic waves. (b) A distance measuring apparatus using the radar principle. (c) A further distance measuring device.
