Title: Camera Array Surgical Microscope


Invention: The invention disclosed here is a compact surgical microscope that provides an increased depth of focus and wide field of view from various angles of the surgical field. Information from multiple wavelengths, including visible and NIR can be overlayed on a single display monitor. The monitor is mounted so that several people can view it at the same time, with no neck or shoulder strain.


Background: Conventional surgical microscopes designed for microsurgery take some time to master and only allow up to two users. In addition, surgeons are constantly having to fix their eyes on the eyepiece. Current microscopes have a low depth of field, low resolution, limited field of view, and are unable to provide other information beyond a stereo view of the surgical field.
