Abstract: An optical measurement system calculates a distance between an optical system and a measurement object based on reflected light beams corresponding to cores, compares a value indicating the distance with a threshold value for each of the reflected light beams, calculates an average value of all the values indicating the distance when the values in the reflected light beams corresponding to all the cores are equal to or greater than the threshold value or the values are less than the threshold value, and calculates an average value of the values indicating the distance which are equal to or greater than the threshold value or an average value of the values indicating the distance which are less than the threshold values when the values corresponding to some cores are equal to or greater than the threshold value and the values corresponding to the other cores are less than the threshold value.

Abstract: A confocal measurement device includes a light source that outputs white light, an optical coupler, a sensor head that applies light with a chromatic aberration caused therein to a measurement object, and a spectroscope that acquires reflected light which is reflected by the measurement object and measures a spectrum of the reflected light. The optical coupler is a filter type coupler or a spatial optical system type coupler that brings a first transmission waveform when light is transmitted from a first optical fiber cable to a second optical fiber cable and a second transmission waveform when light is transmitted from the second optical fiber cable to a third optical fiber cable close to each other.
