Design and Prediction of Detection Range for PIR(Passive InfraRed) Lens Using Optical Simulation Program
Recently, development inquiries for passive-infrared(PIR) lenses continue. In general, PIR(Passive Infrared) lenses are arranged in a x b array with a number of Fresnel lenses. PIR(Passive InfraRed) lenses are usually not flat and are mostly round or square. In addition, separate materials should be used that can be passed on to the FIR(Far Infrared). […]
