Abstract
Official abstract text for this publication.
An intensity of radiation emitted from at least two laser diodes of a projecting apparatus is optimized by providing an offset distance between at least two focal points of the at least two laser diodes and providing a maximum value for radiation intensity emitted by each of the laser diodes, irrespective of simultaneous transmission by one of the laser diodes with another of the laser diodes. The intensity of the radiation emitted from each of the at least two laser diodes is adjusted such that an aggregated value of the radiation intensity emitted by all of the laser diodes within a predefined period of time may exceed a threshold value allowed for the maximum permissible exposure to radiation.
First claim
Opening claim text (preview).
What is claimed is: 1. A laser diode projecting apparatus, comprising: at least two laser diodes each emitting radiation towards a respective focal point at a pre-defined wavelength, and wherein the at least two respective focal points are separated from each other by at least an offset distance; a photodetector operative to measure light intensity near the laser diode projecting apparatus; a processor operative to change the offset distance between the at least two focal poin…
