| Zusammenfassung: | A material haze detection method and apparatus. The method comprises the following steps: optionally primary detection: performing primary detection on a material to obtain a material having no visually visible defects on the surface; and haze detection: detecting haze of the material, wherein in a haze detection device, a photoluminescence signal of the material is filtered out by means of an optical filter module (4) in a receiving optical path, such that the photoluminescence signal is not detected by a detector (5). The haze detection method and apparatus can obtain the detection result of the material haze value and/or distribution more accurately. |
