Abstract
SWIR cameras offer the advantage of higher resolution and smaller optical systems than conventional mid and far infrared optical systems. With the ability of seeing at low illumination conditions at the near infrared region, it can provide the detection of covert lasers. The ability of laser detection introduces the risk of sensor damage when the laser power is above a certain threat level. Smart protection is therefore needed, that is transparent for low laser intensities and limit or block the high laser intensities, and is effective over a wide band of wavelengths. We developed an Optical Power Control (OPC) device that reduces laser power threat to a safe level for a variety of optical systems. The talk presents a novel technology for protection of SWIR cameras against laser threats.
