    Abstract: The invention relates to a method for operating a laser light source, more particularly, for scanning in a confocal laser scan microscope, whereby the laser light source (3) is supplied with power by means of a power unit. In order to enhance service life of the laser light source (3) and reduce operating costs, the laser light source (3) is operated with the required power almost exclusively during effective beam utilization time, preferably during data capture. By using a pulsating laser light source, effective beam utilization time, especially data capture, is synchronized (14) substantially with the emission cycle of the laser light source.

    Abstract: The invention concerns a device for the confocal measuring of surfaces inside cavities of the body, specially to measure the surface profile (1) of teeth (2) in the mouth cavity. Said device has a probe (3) that can be introduced into the cavity of the body, a light source feeding the probe (3), a detector picking up a light signal (5) and a processor (6) to digitalize the detected signal transforming it into a tridimensional representation. The device is designed using a simple construction and enabling an error free scanning of the surfaces. To this end, the probe (3) is designed as a rotary scanner having at least one deviating device (7) deflecting the light beam (9) in the direction of the surface that is to be measured (1), the deviating device (7) can be positioned in another scanning axis (10) to forward the rotating light beam (9), and the detector (5) comprises a device for sequential or simultaneous scanning of several focal planes, both with regards to specular reflection and to weak scattered light or fluorescent light of the focal plane concerned.
