Abstract
Digital image acquisition and display of field emission scanning electron micrographs face limitations in terms of detail recognition, sampling of high resolution information, image output and storage space for high pixel density images. The image acquisition and image output of a JEOL JSEM-890 “in lens” field emission SEM were digitized and several approaches for adequate access to the scanned electron probe data have been developed. Images are acquired digitally in 3×4 VGA format (in multiples of 640×490 pixels) and stored in a RECOGNITION CONCEPTS INC. image processor (Trapix Plus). The images are displayed on workstation monitors with 1280×1024 format (HITACHI CM2085MU), and image documentation is done by several techniques of varying output quality. Low quality image documentation on plain paper can be obtained using a laser jet printer (HEWLETT PACKARD: Laser Jet III). High quality output is provided by a video printer utilizing special but inexpensive paper (SEIKOSHA VP350H). In addition, conventional analog CRT output and CRT photography on 4×5 inch POLAROID (Type 55 Positive/Negative) film is used.
