An innovative surface plasmon resonance (SPR) sensor is constructed to achieve ultraviolet (UV) imaging. The SPR sensor is fabricated using a gold-coated prism, which is then overlaid with an azo-polymer film as a UV sensing layer. The refractive index of the azo-polymer decreases during UV light irradiation. The changes of the refractive index influence the intensity of the light reflected from the...
A lens-array-based integral imaging camera is studied in this work, which consists of a lens array, a main lens and a CCD camera. The lens array is placed on the object side of the main lens, thus can provide wider stereo baseline than other lens-array-based integral imaging cameras where the lens array is usually placed on the sensor side. However, the image captured by this system presents severe...
