Paper Abstract

A new Intense Point Source (IPS) is capable of focusing twice as much light into an optical fiber as the traditional elliptical reflector system. The special feature of the IPS system is the ability to focus a linear light source to an extremely small point, such as at the tip of a optical fiber bundle. The scaling law of the regular reflector requires the increase of the physical dimension of the light source and thus leads also to a larger focused image. Unfortunately, the light intensity does not scale with the increased power. The new IPS system consists of a linear light source and a compound Orthogonal Parabolic Reflector (OPR), properly matched to produce an intense image at the focal point of the system. Intensity at the focal point can be increased simply by increasing the linear length of the light source.
