应用高功率激光器作为光学火印,将全息图案烧印到30到40个原子厚的薄膜内,这是一种摄制全息照片的新技术,全部过程只要几个毫微秒。这种方法避免了通常的胶片曝光和显影,也避免了笨重而昂贵的 The application of a high-power laser as an optical print burns a holographic pattern into a film of 30 to 40 atoms thick, a new technique for producing holograms that takes only a few nanoseconds. This method avoids the usual film exposure and development, but also avoids bulky and expensive
