Abstract
A confocal microscope having a scanning head in the form of a hand piece which may be placed at selected locations on the body of a patient. A laser beam is scanned in orthogonal (horizontal and vertical) directions by scanners which drive scan mirrors, which are closely adjacent to each other. The optics include an objective lens and a telescope lenses that image the objective lens entrance pupil between the scan mirrors. Scanner is a pulse driven resonant scanner which is feed back controlled to maintain scanning rate and can change the scan angle and obtain dynamic, electronic image zooming without changing the positional relationship of the telescope.
