The method of producing the rainy sensor, the rainy sensor and the rainy sensor for the especially automobile

摘要

It is proposed that it forms the stratified section body which consists of the photo polymer where volume hologram is processed inside with (3) the optical guided wave body which is arranged inside the glass (22) in the rainy sensor and the rainy sensor for the especially automobile which it possesses, the light ray of holographic type (4) planer coupling element for incidence and radiation. The photo polymer section body (3) the guided wave body core (1) and the guided wave body overcoat (2) is arranged between. Because of this easy production characteristic and the guided wave body inside the glass (22) increase of flexible characteristic of arrangement is brought.
