Bas Hulsken (Inventor), Sjoerd Stallinga (Inventor)

Research output: Patent


The present invention relates to the field of digital pathology and in particular to whole slide scanners. Autofocus imaging can be performed by sampling a first number of pixels of a primary image sensor which is a time delay integration (TDI) sensor, and sampling a second number of pixels of an autofocus image sensor, wherein the second number is between one quarter and three quarters of the first number. Thus, continuous autofocus for rapid light scanning may be provided based on an additional image sensor that is tilted with respect to the optical axis.
