METHOD AND APPARATUS FOR FAST FOCUS IMAGING BIOLOGIC SPECIMENS

摘要

A method and apparatus for imaging a biologic fluid sample quiescently residing within a chamber is provided. The method includes the steps of: a) positioning the chamber at a Z-axis position relative to an objective lens having a lens axis, wherein the Z-axis is parallel to the lens axis; b) moving one or both of the chamber and the objective lens relative to one another at a velocity along the Z-axis; and c) creating one or more images of the biologic fluid sample as one or both of the chamber and the objective lens are moving at a velocity relative to one another within a focus search range along the Z-axis.
