| titleOfInvention | Frost detection element and frost detection method |
| abstract | (57) [Summary] [Problem] A simple and inexpensive frost detection element and method for detecting frost using simple, high sensitivity, quick response, and excellent durability utilizing nonlinear optical characteristics. And provide. SOLUTION: The frost detection element of the present invention has a high refractive index thin film having a real part n of a complex refractive index of 1.8 or more and a contact angle of water of 60 ° or more on a substrate, A light emitting element and a light receiving element are provided on the surface on the opposite side of the high refractive index thin film. In this frost detection element, the high-refractive-index thin film reflects the light emitted from the light-emitting element, detects the reflected light with the light-receiving element, and the point in time when the reflectance falls below a certain reflectance or the reflectance sharply decreases. The time point is determined to be the time of frost formation. |
