Mid-Infrared Light Tuned for Sensing with New MIT Chip

MIT researchers have developed a chip-based optical device capable of dynamically controlling incoming mid-infrared light, potentially leading to more precise thermal imaging, chemical sensing, and pollution monitoring. Each microscopic pixel of the device’s lens can independently control infrared light, allowing for focus changes without the need for moving parts, a key advancement for creating miniaturized and faster sensing systems. The system, detailed in a paper published in Nature Communications, was built using mostly conventional semiconductor manufacturing processes, suggesting a viable path toward industrial-scale implementation. “This could give us more information…
