Abstract:
System for acquiring a digital image of a sample on a microscope slide. In an embodiment, the system comprises a stage configured to support a sample, an objective lens having a single optical axis that is orthogonal to the stage, an imaging sensor, and a focusing sensor. The system further comprises at least one beam splitter optically coupled to the objective lens and configured to receive a field of view corresponding to the optical axis of the objective lens, and simultaneously provide at least a first portion of the field of view to the imaging sensor and at least a second portion of the field of view to the focusing sensor. The focusing sensor may simultaneously acquire image(s) at a plurality of different focal distances and/or simultaneously acquire a pair of mirrored images, each comprising pixels acquired at a plurality of different focal distances.

Claim (Index 55):
A method for automatic, real-time focusing, wherein the method comprises using a processor in a slide scanner to, for each portion of a sample to be scanned:\n prior to, at, or following the portion of the sample being sensed by an imaging sensor,\n acquire a focusing image of the portion of the sample from a focusing sensor, wherein a portion of a field of view that is sensed by the focusing sensor is offset from a portion of the field of view that is sensed by the imaging sensor, such that, in a scan direction, the focusing sensor senses a portion of the field of view before, at a same time that, or after the imaging sensor senses that same portion of the field of view, and wherein one point on the focusing sensor is parfocal with the imaging sensor, \n for each a plurality of positions on the focusing sensor, calculate a contrast measure for a region of the focusing image corresponding to that position on the focusing sensor, \n determine a relationship between the focusing image and a main image of the portion of the sample acquired by the imaging sensor, \n determine a peak for the relationship, \n update a target surface based upon a distance between a location on the focusing sensor corresponding to the peak and the parfocal point, and \n determine a position for an objective lens that moves to a next target surface; and \n acquire an image of the portion of the sample from the imaging sensor while the objective lens is at the determined position.
