Waveguide type compact optical scanner and manufacturing method thereof |
摘要 |
A waveguide type reduction type image sensor has a waveguide type light source having a light emitting element and a substrate including optical waveguides having a planar waveguide and a tapered waveguide. The waveguide type reduction type image sensor also has a light detecting section having a microlens array, an optical waveguide substrate and a CCD array. The microlens array converges reflected light from an original onto the incident face of the optical waveguide substrate. The optical waveguide substrate has L-shaped optical waveguides for guiding the converged light to the CCD array located on a substrate face perpendicular to the incident face. The CCD array converts the guided light to an electric signal and outputs this electric signal. A manufacturing method of this waveguide type reduction type image sensor is also shown.
