Study of Ceramic Coatings as a Novel Optical Imaging Tracking Material Using Plasma Spray Method

The aim of this work is to measure the optical reflective properties of plasma sprayed ceramic coatings on glass substrates. The coatings are made with Al₂O₃-TiO₂ powders and are assessed by scanning them with an optical computer mouse. It is shown that mouse movements are smoother on ceramic surfaces than on a standard test pad and tracking performance is more stable, indicating that the reflective properties of ceramic-coated glass are better than those of a typical mouse pad. The ceramic coatings are also shown to have the potential to improve resolution in image recording devices.
