Article Synopsis
- - Interest in the eSWIR (extended Short-Wave Infrared) band is increasing due to improvements in detector technology, specifically using materials like mercury cadmium telluride and type-II superlattice.
- - Advances in design and fabrication enable the optimization of detector characteristics such as size, weight, and power, making smaller detectors desirable in certain applications.
- - The research investigates how the size of eSWIR detectors impacts imaging performance under various illumination conditions, particularly analyzing signal-to-noise ratio (SNR) and comparing active versus passive imaging techniques for long-range object discrimination.
Daytime low-light conditions such as overcast, dawn, and dusk pose a challenge for object discrimination in the reflective bands, where the majority of illumination comes from reflected solar light. In reduced-illumination conditions, the sensor signal-to-noise ratio can suffer, inhibiting range performance for detecting, recognizing, and identifying objects of interest. This performance reduction is more apparent in the longer wavelengths where there is less solar light.
