Abstract
An error of a measured distance is reduced. An optical measurement device () includes: a light source (), which emits lights; a sensor head (), which condenses reflected lights reflected by a target (TA); a light reception portion (), which is configured in a manner that each of a plurality of pixels is capable of detecting a light reception amount, and which obtains a light reception amount distribution signal of each pixel for the condensed reflected lights; a measurement portion (), which measures a distance from the optical measurement device () to the target (TA) based on the light reception amount distribution signal; and a correction portion (), which corrects the measured distance that is measured based on a predefined characteristic value in a waveform of the light reception amount distribution signal.
