Analyzing optical dual-wavelength-band cameras operating in short-wave and medium-wave infrared spectral regions.

This study analyzed the optical and laser spot acquisition capabilities of a newly developed dual-wavelength-band camera. The camera performance was evaluated using a 3.0 m × 1.8 m Styrofoam target and a 70-mJ laser target designator; mid-infrared images were acquired based on the target distance, and a laser beam was irradiated onto the target to detect laser spots. The dual-wavelength-band camera demonstrated target recognition and spot detection ranges of 3 and 2 km, respectively. The results demonstrated that laser spot images could be obtained with a laser reception power of 65 μW or higher.
