An illumination system is provided to enable speed dome camera systems
with a minimum of weight increase and existing motor designs to be used
in conditions where the ambient illumination is insufficient for
surveillance needs. A laser illumination system is divided and dispersed
in the system, with its heavy components, namely the power supply, heat
sinks, and laser beam generator mounted outside the speed dome and only a
lightweight fiber optic cable output mounted adjacent to the speed dome
camera. The key innovation in the present invention is having only a
laser beam delivered over an optical slip joint rather than power for a
laser, allowing for a higher speed of orientation of the camera. A
pulsing system is used to avoid flashback within the speed dome.
