In a process for the display of three-dimensional video images, in which at least two associated stereoscopic left-hand and right-hand partial images are electro-optically sensed at a given read-in frequency and the partial images are then sequentially reproduced on a display, the sensing of the two partial images takes place with a constant delay time with respect to each other, so that a delay which remains constant is ensured between the image formation in the camera and the reproduction of the partial image.

Process and apparatus for displaying three-dimensional video images

The invention relates to a method and apparatus for controlling the quantity of emitted light in an optical measuring head. The control of the emitted light quantity of a laser diode mounted in the optical measuring head is dependent upon the stray light characteristics of the workpiece and is achieved by controlling the pulse width of the laser diode. The light pulses are synchronized with the machine clock frequency of the coordinate measuring apparatus on which the measuring head is fixedly mounted such that the center of the pulse coincides always with the counter strobe of the measuring system of the coordinate measuring apparatus.
