    Abstract: An illumination device includes a light source, a micromirror array including a plurality of micromirror actuators, an illumination optical unit, and an optical sensor unit having a sensitive sensor surface. The illumination light is guided onto the micromirror actuators and is reflected at the latter and with the reflection in the temporal integral. An on beam is reflected by the micromirror actuators in a respective on tilt position via the illumination optical unit to an illumination application. An off beam is reflected by the micromirror actuators in a respective off tilt position alongside the illumination optical unit. The sensor unit is arranged in the off beam, in order to capture a radiation guided in the off beam at least in the case of a fault. The sensor unit is oriented in such a way that the sensor surface lies obliquely with respect to a main incidence direction of the radiation.

    Abstract: An irradiation apparatus includes a radiation unit for the emission of radiation in the form of a beam, a first microlens arrangement, downstream of the radiation unit, having a multiplicity of convergent microlenses, for dividing the beam into one partial beam per convergent microlens, and a convergent lens, downstream of the microlens arrangement, that overlays the partial beams, in an irradiated area. The microlenses have a first group and a second group. The microlenses in each group are identical, but the microlenses in the first group differ from the microlenses in the second group from their shape, size and/or focal length, so that a first region of the irradiated area, which is irradiated via the microlenses in the first group, differs from a second region of the irradiated area, which is irradiated by the microlenses in the second group, from its shape and/or its size.

    Abstract: A projection device may include at least one first laser device and one second laser device, which is arranged opposite the first laser device. A prism is arranged between the two laser devices, wherein a polarization-dependent mirror device is arranged in the prism in such a manner that the beam of the first laser device is reflected in a direction that extends opposite the direction in which the beam of the second laser device is reflected. The polarization of the beam of the second laser device is then rotated, and the beam is deflected back to the polarization-dependent mirror device. The beam of the second laser device now passes through the mirror device without reflection due to the change in the polarization of the beam of the second laser device, such that two superposed laser beams of different polarization are available at the output of the projection device.
