Surveillance results with Laser illumination I Filter Laser pulse conventional camera + laser camera + filter Camera chip sensitivity Suppressing disturbing LED pulse ambient light by filters. visible light Visible light will be λ reduced to a minimum. blue red Bandpass-filter blocking visible light. High efficient by using narrow bandwidth (2-4 nm) Additional suppression of polarized light (e.g. reflection of sun light) by a polarized filter 20.11.2018 7
Surveillance results with Laser illumination Applications Without Laser illumination Laser illumination Camera without Filter Laser illumination + Filter Without Laser illumination Laser illumination Camera without Filter Laser illumination + Filter 20.11.2018 8
