The advantages of optical fiber sensors include their miniaturization, strong anti-interference
ability, high sensitivity, low cost, and fast response speed. They can be used for in situ …

Abstract Tunable optical Fabry–Perot Interferometers (FPIs) have been designed as filters
on sensors for gas detection in the mid infrared range where their radiation absorption is at …

We propose a pixelized gradient thickness color filter as the compact and space-saving
element for achieving simultaneous imaging and spectroscopy using a single image sensor …
