摘要： An exoscope with enhanced depth of field imaging is provided. The exoscope includes first and second sets of optical devices, the first set having a fixed image plane, the second set having a variable image plane adjacent the fixed image plane of the first set. The second set includes at least one variable device configured to change the position of the variable image plane. A beamsplitter splits light from a combined optical path of the first and second set to respective image devices of the first and second set of optical devices. A controller controls the at least one variable device to change the position of the variable image plane relative to the fixed image plane, combines images acquired by the respective image devices, and controls a display device to render a combined image.
