A laser diode projecting apparatus which comprises: 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; and a power controller operative to control the intensity of the radiation emitted from each of the at least two laser diodes; and wherein the aggregated value of the radiation intensity emitted by all of the at least two laser diodes within a predefined period of time, exceeds a threshold value allowed for the maximum permissible exposure to radiation. |
