Light wave distance measuring apparatus
A reference electrical signal oscillated by the main oscillator (11) has two kinds of frequencies (f1, f2) which are different from each other and any one of which is alternatively selected, a sampling signal is synchronized with the reference electrical signal once every n times, and a frequency (fs) of the sampling signal is an average value of the two kinds of frequencies (f1, f2) of the reference electrical signal, and the A/D conversion portion carries out at least one A/D conversion per period of the reference electrical signal and the received electrical signal based on the sampling signal.
