Abstract
A range finding apparatus () generates a plurality of range finding signals. The range finding apparatus () generates transmission light acquired by performing at least one of quadrature modulation and polarization modulation on an optical carrier wave by using each of the generated range finding signals. The range finding apparatus () transmits the generated transmission light. The range finding apparatus () receives reflection light which is the transmission light reflected by an object to be measured. The range finding apparatus () extracts a reception signal corresponding to each of the range finding signals by demodulating the reflection light. The range finding apparatus () computes a distance to the object to be measured by using any one or more of the extracted reception signals.
