They’re nearly invisible to the human eye, but smart dust sensors are now being embedded in bridges, factories, and even ...

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

In this paper, a novel Sagnac Interferometer (SI) based chalcogenide Photonic Crystal Fiber (PCF) temperature sensor is theoretically and numerically analyzed operating in the mid infrared (MIR) ...

We present a technique for designing the angle-sensing infrared detectors with subwavelength dimensions. The proposed detector is composed of a two-element long-wave infrared (LWIR) biomimetic antenna ...
