Abstract
In an optical instrument, fiber optics are employed to receive light from a linear filament. The fiber optics are arranged into a plurality of light receiving bundle ends distributed around the linear filament and shaped into narrow rectangular slits aligned with the filament. The fibers from each of the receiving ends are equally distributed between two transmitting ends which direct the light through cylindrical lenses to opposite sides of a rotating filter wheel in a paddle wheel configuration. Light beams from the transmitting ends of the fiber optic bundles pass through filters on the filter wheel to additional fiber optic bundles which carry the received light to a probe.
