Abstract: We propose and develop a two-parameter optical fiber sensor based on photopolymer microtips, which may measure both refractive index (RI) and temperature simultaneously. We fabricate the ...
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 ...
Abstract: This paper describes a low-cost fiber optical temperature sensor technology with wide operation temperature ranges and immune to complex electromagnetic environments. Using a low-cost ...
