| Abstract: | An up-conversion materials outputting green light,which can store ultraviolet and visible image and convert infrared image into visible image,was investigated.The possibility of image storage and parallel incoherent image subtraction was experimentally demonstrated,using electron-trapping film whose thickness is approximately 200μm.The experimental results show that this material has many attractive advantages.such as:erasability,rewritability,high resolution,high speed,large response linearity and capable of analong and parallel operations,for application in optical storage and optical signal processing. |
