Abstract
A shape measurement instrument includes a plurality of transmitterstowhich radiate signals having different waveforms or phases, receiverstowhich receive signals reflected from an object O, correlation unitstowhich obtain correlation waveforms between waveforms of the signals received by the receiversto, and the signal radiated by a transmitter radiating the received signal of the transmittersto, and a shape estimation unitwhich extracts a quasi-wavefront based on the correlation waveforms obtained by the correlation unitstoand estimates a shape of the object O based on a relationship between the quasi-wavefront and the object O. As a result, a period of time required to measure an object shape can be significantly reduced.
