Optical measurement device

An optical measurement device, comprising:

• an optical sensor which measures an optical waveform of a reference object or a measurement object;
• a learner which receives a first optical waveform of the reference object from the optical sensor and learns frequency characteristics of the first optical waveform;
• a filter generator which analyzes the frequency characteristics of the first optical waveform and generates a frequency filter;
• a frequency modeling unit which receives a second optical waveform of the measurement object from the optical sensor and models frequency characteristics of the second optical waveform;
• and
• an optical characteristic detector which calculates an optical characteristic index of the second optical waveform based on an output value of the frequency modeling unit and the frequency filter,
• wherein the learner includes:
• a domain converter which receives the first optical waveform and converts the first optical waveform into a frequency domain;
• a weighted value applying unit which applies at least one weighted value filter to an output value of the domain converter;
• and
• a classification unit which classifies a kind of the first optical waveform based on an output value of the weighted value applying unit.
