DISPOSITIF D'ANALYSE OPTIQUE ET DISPOSITIF D'APPRENTISSAGE MACHINE UTILISÉ POUR LE DISPOSITIF D'ANALYSE OPTIQUE ET PROCÉDÉ ASSOCIÉ

摘要

The present invention refers to an optical analysis device 100 for performing output correction of a detector used for an optical analysis device by use of a plurality of light amounts and with simple configuration and for correcting nonlinearity of a light detector 4 which detects light to obtain an output value, and the optical analysis device 100 includes: a light source 1 which irradiates the light; a measurement cell 3 into which the light irradiated from the light source 1 is inputted; the light detector 4 which detects light outputted from the measurement cell to obtain the output value; a learning part 51b which uses the output value of the light detector 4 before the correction and an output value in a linear region of the light detector 4 or known concentration of a sample gas introduced to the measurement cell 3 to perform machine learning of a correction model for linearly correcting the output value of the light detector 4; and a saving part 51c which saves the correction model obtained by the learning part 51b.
