Contrary to popular belief, most property crimes—including burglaries and package theft—happen during the day, not under cover of darkness. But night still brings unique challenges: fewer people ...
IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...
Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...
