We present an experimental study of subwavelength hole arrays in thin metal films employed as surface-enhanced optical sensors operating in the mid-infrared. The extremely narrow surface plasmon ...

Labeling bottles manually takes a good chunk of time and effort. Addressing this, the YouTube channel Easy Home Made Projects ...

Abstract: This paper investigates the feasibility of using commercially available, low-cost IR reflective sensors for micro- to sub- microscale position measurement and control. These sensors are ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use ...
