Title:
光学窓の清浄化装置、エンジンおよびその光学窓の清浄化方法
Document Type and Number:
Japanese Patent JP6980319
Kind Code:
B2
Abstract:
An apparatus for cleaning a surface of an optical window includes a first electrode that is provided inside the optical window and is covered with a dielectric material forming the optical window. A second electrode is provided around the optical window and is exposed on at least one surface of the optical window. A power supply is electrically coupled between the first electrode and the second electrode. The apparatus further includes a controller that controls the power supply so as to generate dielectric barrier discharge along the surface of the optical window by applying a high-frequency or pulsed voltage between the first electrode and the second electrode.
