Abstract
An optical system is proposed which is configured to detect an obscuration of the optical components and to optionally initiate measures, which either warn the driver and/or activate a heater which reduces the detected obscuration of the image. The system is controlled by a method for detecting an obscuration, which comprises a high reliability for detecting obscurations through the evaluation of additional sensors.
