Abstract

The present invention provides a low profile fiber optic sensor (100) including a fiber optic fan having a collecting end (103) with a light-collecting portion (106), a terminal end (108), a core material extending from the collecting end to the terminal end and an outer cladding. The fiber optic fan may be made from a plurality of optical fibers or a light pipe. The light-collecting portion (106) is formed into a pattern that has a shape with a first side and a second side. A light source (104) is positioned on the first side of the pattern with an opaque light shield (105) positioned about the light source (104). To enhance the performance of the sensor, an optical lens is coupled to the core material on the first side of the pattern to enhance detection of the light. The lens may be an array of microprisms (535), spheres or hemispheres.
