Title (EN) CALIBRATION OF A SENSOR
(FR) ÉTALONNAGE D'UN CAPTEUR
Abstract:
(EN) In one example of the disclosure, an uncalibrated sensor may be calibrated. Calibrated sensor data is obtained. The data relates to an amount of light transmitted through an ink solution of a first colour as a function of ink concentration. An amount of light transmitted through an ink solution of the first colour is measured, using the uncalibrated sensor, at a plurality of ink concentrations. A calibration factor relating the light transmission of the calibrated sensor for the first colour and the light transmission of the uncalibrated sensor for the first colour is determined, using a processor, based on the obtained data and the measurements.
(FR) Dans un exemple, la présente invention concerne un capteur non étalonné qui peut être étalonné. Des données de capteur étalonné sont obtenues. Les données concernent une quantité de lumière transmise à travers une solution d'encre d'une première couleur en fonction de la concentration d'encre. Une quantité de lumière transmise à travers une solution d'encre de la première couleur est mesurée, à l'aide du capteur non étalonné, à une pluralité de concentrations d'encre. Un facteur d'étalonnage relatif à la transmission de lumière du capteur étalonné pour la première couleur et à la transmission de lumière du capteur non étalonné pour la première couleur est déterminé, à l'aide d'un processeur, sur la base des données obtenues et des mesures.
