METHOD OF CHARACTERIZING AN OPTICAL SENSOR CHIP, METHOD OF CALIBRATING AN OPTICAL SENSOR CHIP, METHOD OF OPERATING AN OPTICAL SENSOR DEVICE, OPTICAL SENSOR DEVICE AND CALIBRATION SYSTEM
Means are suggested for calibration in the field of optical sensors, e.g. characterizing and calibrating an optical sensor chip. In order to address complexity of sensor data with high accuracy the optical sensor, e.g. an optical sensor is not provided as an already calibrated unit. Rather, sensor response data may be recorded in a defined or standardized environment, e.g. at a production line, and with high precision. This high standard sensor response data can be obtained on a per device basis and, thus, is referenced with an unambiguous chip identification number, chip ID. The sensor data is complemented with a dedicated calibration algorithm which can be tailor-made to fit the optical sensor or the optical sensor chip. In order to retrieve the sensor response data and the calibration algorithm both can be made available by means of the chip ID, for example.

Then the gas to be measured is decomposed using the means (11, 12) for decomposing the gas of the gas sensor arrangement. A second sensor signal is acquired and from the second sensor signal at least one decay data point is determined. Finally, an absolute gas concentration is determined from a gas concentration function by evaluating the gas concentration function at least for the initial data point and the decay data point.
