Abstract: An arrangement or a projection headlight with a modulator, in particular with a DMD, is disclosed. In this case, a projection lens of the arrangement not only images the image content of the modulator in the surrounding area, but also images the surrounding area on the modulator. The modulator can thus guide the imaging of the surrounding area to a camera and reflect light from a light source into the surrounding area.

Abstract: An illumination device includes a light source, a micromirror array having micromirror actuators, switchable in each case between an on state and an off state, an optical unit, and an optical sensor unit. The light is guided onto the array and proportionally at a respective one of the actuators in an on tilt position is reflected to an illumination application, and in an off tilt position is reflected to the optical sensor unit. The device is configured such that a first actuator, which is in an on state in the on tilt position, is brought to the off tilt position for a first test interval, and a second actuator, which is in an off state in the off tilt position, remains in the off tilt position for the first test interval. A radiation power incident on the sensor unit during the first test interval is detected by the sensor unit.
