Method and apparatus for controlling coordinate displacements of a platform |
摘要 |
<p>The field of the invention is a combination of a microscope and an interactive image analysis system comprising a camera and a computer work station. The purpose of the invention is to facilitate the interactive control of coordinate displacements of the stage of the microscope. For each coordinate x and y an electromechanical control channel is established. At the input of the control channel two cascaded wheels in a coaxial arrangement and two angle encoders are used as a detached, independent tool which is not kinematically linked to the stage. In the middle of the control channel, the pulses of the angle encoders undergo a non-linear transformation. A processor performs a calculation which discriminates between slow displacements and fast displacements. At the end of the control channel, a flat, easily accessible platform of the microscope stage has two working areas, one for manual previewing and one for interactive scanning of a specimen. <IMAGE></p> |
