Asynchronous laser pulse detection integrated into a multispectral SWIR/VIS single aperture 2-chip zoom camera

In defense applications, multispectral imaging plays a crucial role in enhancing scene awareness by providing contrast-based information across visible (VIS) and shortwave infrared (SWIR) spectral bands. Beyond conventional imaging, the detection of short-pulsed laser emissions from potential hostile sources such as rangefinders and target designators is increasingly vital for early threat identification and platform protection. We present a unique multispectral imaging system featuring a single-aperture zoom objective capable of simultaneous contrast-based VIS-SWIR imaging within the identical field of view and event-based asynchronous laser pulse detection (ALPD).
