ZnO固体象存贮屏是一种具有存贮性能的X射线象转换器,由ZnO光导层和ZnS电致发光粉末层所组成。虽然目前其灵敏阈(约为1伦/分),不如X射线荧光屏,但亮度约为1呎一朗伯,且具有存贮性,存贮时间可以是几分钟或几小时。同时优点在于操作人员可以不在现场观察转换图象,避免“吃”X射线,因此可期待用于某些非破坏性检查,如铝合金探伤及其他一些特殊的场合,也可以用于某些医疗部门。
ZnO solid state image storage screen is a storage performance of the X-ray image converter, composed of ZnO light-emitting layer and ZnS electroluminescent powder layer. Although the current sensitivity threshold (about 1 Lun / min) is not as good as that of an X-ray screen, the brightness is about 1 foot-1 lambertian and is storable and can be stored for a few minutes or hours. At the same time the advantage is that the operator can not observe the conversion images in the field, to avoid “eat” X-ray, it can be expected for some non-destructive inspection, such as aluminum alloy flaw detection and other special occasions, can also be used for certain medical department.
