Imaging by scanning electron beam

In the direct method, an X-ray-sensitive vidienn TV camera direedy converts the X-ray image into an electronic charge pattern on a photoconductive target, which is read out by a scanning electron beam and displayed visually on a TV monitor. [Pg.1092]

The specimen is scanned point by point by the electron beam as shown in Fig. 4. SEs that are emitted from the specimen s surface (1) are collected by the detector (2) and undergo a video processing (3), leading to the image formed on the video screen (4). [Pg.3219]
