制备原理:紫外线示波记录纸是一种光显影材料,主要是利用其内部潜影。第一次瞬时高能量曝光(包括紫外线、X射线、γ射线以及电子束等高能量短波幅射)生成的潜影基本上全是内部潜影,继而以低能量光源(漫射的可见光)第二次曝光进行光显影,使内部潜影加强而成为可见影象。在光显过程中,未受第一次曝光影响的部分(背影),由于只生成表面潜影,遮盖率很低,仅产生微弱影象(背景密度),从而提高了反差使记录清晰。
Preparation principle: UV light recording paper is a light-developing material, mainly the use of its internal latent image. The first instantaneous high-energy exposure (including high-energy short-wave radiation such as UV, X-rays, gamma rays, and electron beams) produces latent images that are essentially all internal latent images, which in turn are illuminated with a low energy light source (diffuse visible light) Second exposure to light development, so that strengthening of the internal latent image as a visible image. In the light exposure process, the portion not affected by the first exposure (back view) had a low contrast due to the generation of a surface latent image, and only a weak image (background density) was generated, thereby improving the contrast and making the recording clear.
