Abstract
The invention relates to a method for adjusting focus in an automated microscope. The method may comprise the steps of: providing an optical detector for image acquisition, wherein the optical detector comprises an array of sensor pixels; designating a region of interest in the array of sensor pixels to emulate a confocal aperture; directing a light beam to illuminate an object according to a predefined pattern, thereby forming an image of the illuminated pattern at the optical detector, wherein the image of the illuminated pattern substantially overlaps the designated region of interest; detecting a light intensity from sensor pixels located within the designated region of interest; and adjusting a relative focal position of an objective lens based on the detected light intensity.
