Method and device for visualizing the position of a laser beam

Photodiodes (1,2) detect a laser beam. An alternating current portion of the photodiodes is converted into voltages. Comparators (7) suppress background. Memory devices store signal positions generated by the laser beam. Luminous diodes (13,14) display the signal positions stored in the memory devic...

Zusammenfassung:Photodiodes (1,2) detect a laser beam. An alternating current portion of the photodiodes is converted into voltages. Comparators (7) suppress background. Memory devices store signal positions generated by the laser beam. Luminous diodes (13,14) display the signal positions stored in the memory devices. An Independent claim is also included for a device for making a laser beam position visible in bright surrounding light with a detector for laser beams and a display device for showing the laser beam's position.
