OPTICAL ANALYSIS DEVICE, AND MACHINE LEARNING DEVICE USED FOR OPTICAL ANALYSIS DEVICE, AND METHOD FOR THE SAME

The present invention refers to an optical analysis device for performing output correction of a detector used for an optical analysis device. The optical analysis device includes a light source which irradiates light, a measurement cell into which the light irradiated from the light source is inputted, a light detector which detects light outputted from the measurement cell to obtain an output value, a learning part which uses the output value of the light detector before the correction and an output value in a linear region of the light detector or known concentration of a sample gas introduced to the measurement cell to perform machine learning of a correction model for linearly correcting the output value of the light detector, and a saving part which saves the correction model obtained by the learning part.
