"Here, infrared imaging is demonstrated by nonlinear up-conversion to the visible in an ultra-compact, high-quality-factor lithium niobate resonant metasurface. Images with high conversion efficiency and resolution quality are obtained despite the strong nonlocality of the metasurface. The possibility of edge-detection image processing augmented with direct up-conversion imaging for advanced night vision applications is further shown."
spectral response if flat from 450 to 950 nanometers is +/- 7%. The response is typically down 50% at 400 and 1030 nm. Narrow angle light sources such as lasers, can be measured in microwatts instead of microwatts/cm2.
The Sharp GP1FA313RZ optical receiver can do 15.5 megabits per second.
