SUMMARY A computer control system for electron microscopy is proposed; it consists of functionally distinct microprocessors communicating via a central microprocessor (the supervisor) by direct memory access or a common data bus. The control functions such as digital beam scan, accelerating voltage, focusing, etc., are controlled by distributed microprocessors under the direction of the supervisory microprocessor. The system includes a framestore for image storage and a special high speed processor that contains a microcode library of functions. The system is used for interactive real‐time image analysis by comparison of calculated images and processed experimental images.
