The present invention provides an optical displacement meter which
performs a profile search for performing positional adjustment of a
profile shape. The optical displacement meter includes: an amplifier for
amplifying a reception light signal from a two-dimensional light
receiving device; profile computing means capable of computing a profile
shape of the object to be measured on the basis of an amplification
signal obtained by the amplifier in a point in the first direction by the
reflection light of the light emitted from the projector; a display unit
capable of displaying the profile shape of the object to be measured
computed by the profile computing means; registered-profile designating
means for designating a registered profile as a reference of a profile
search from profile shapes displayed on the display unit; and profile
matching means for performing a profile search to find a match between an
input profile shape and the registered profile designated by the
registered profile designating means and, on the basis of a result of the
profile search, rotating or moving the input profile shape.
