Abstract
A light scattering patch device and preparation method thereof is disclosed. The light scattering patch device is composed of a patch, an air gap, and a tapered optical fiber; the patch is a transparent patch; a refractive index of the patch is greater than a refractive index of a biological tissue; a tip, a tapered transition zone and a partial unstretched zone of the tapered optical fiber are embedded in the patch, and the air gap is formed between the tip and the tapered transition zone of the tapered optical fiber and the patch. The method of preparing the light scattering patch device comprises: first preparing the tapered optical fiber, then performing hydrophobic modification on the surface of the tapered optical fiber; placing the tapered optical fiber in an uncured polymer and curing the uncured polymer, and pulling the unstretched part; connecting the unstretched part of the tapered optical fiber.
