Abstract: Method for operating an interior lighting device for a motor vehicle, comprising a lighting device and a sensor device, which senses a position of an operator control object for the lighting device in its sensing area, wherein the lighting device is controlled on the basis of sensor data from the sensor device, wherein the lighting device has multiple actuatable lighting units that each have an associated local section defined in the sensing area, wherein when an operator control object is detected in a local section, the associated lighting unit is activated and activated lighting units not associated with the local section are deactivated.

Abstract: Method for operating an interior lighting device (1, 1?, 1?) for a motor vehicle (8), comprising a lighting device (L, L?) and a sensor device (S, S?), which senses a position of an operator control object (6) for the lighting device (L, L?) in its sensing area, wherein the lighting device (L, L?) is controlled on the basis of sensor data from the sensor device (S, S?), wherein the lighting device (L, L?) has multiple actuatable lighting units (L1-L3, L1?-L7?) that each have an associated local section (O1-O3) defined in the sensing area, wherein when an operator control object (6) is detected in a local section (O1-O3), the associated lighting unit (L1-L3, L1?-L7?) is activated and activated lighting units (L1-L3, L1?-L7?) not associated with the local section (O1-O3) are deactivated.

Abstract: The invention relates to an ancillary module 7 for making spatially resolved measurements of the focus volume of a light beam focussed by a microscope objective 4. The light beam is especially a laser beam. The invention includes a carrier assembly having a glass plate 8 and sleeves (9, 10) mounted thereon. A piezoelectric scanning tube 12 is held on the sleeves (9, 10) essentially perpendicularly to the glass plate 8. The scanning tube 12 operates to move an optical near-field probe 13a in three mutually perpendicular directions. The optical near-field sensor is preferably a glass fiber 13 which has a tip 13a at one end thereof. This tip 13a scans the laser focus volume. At the other end of the glass fiber 13, either a photodiode 14 is provided with which the light coupled into the glass fiber is detected or a corresponding light detector can be adapted by means of an interface. The two sleeves (9, 10) are displaceable relative to each other for coarsely positioning the scanning tube 12.
