Abstract
Abstract A method for emphasizing a portion of an area of a subject being scanned by a scanning microscope wherein a subject is scanned with a particle probe of the microscope moving at a given scanning speed along a line with a given space between lines and wherein the image is reproduced on the image recording device having a given scanning speed along each image line and a given spacing between the image lines characterized by enlarging selected portions of the image by selectively varying the scanning speed and spacing between the lines of at least one of the particle probe and image recording devices. The method enables producing an enlarged portion of an area of the subject being observed with the surrounding portions of the area being simultaneously produced to enable a significantly faster and more reliable discovery of the portion of the area of the subject which is of interest.

Claim 1
Independent Claim
163 words
In a method of scanning an area of a subject with a scanning microscope, said method including the steps of conducting a particle probe of the scanning microscope over the subject in a line-by-line manner with a given scanning speed along each line and a given spacing between the lines, and reproducing the image on an image recording device in a line-by-line manner by utilizing a given scanning speed along each image line and a given spacing between the image lines with the improvement comprising in the step of conducting a particle probe, continuously varying the scanning speed along each line of the particle probe and continuously varying the spacing between the lines during the scanning of each line while maintaining the scanning speed and spacing between lines constant at the image recording device so that the recorded image contains a magnified portion of an area of the subject with a greater magnification than the image of the portions surrounding the magnified portions.
