Description

A laser feedback microscope that uses a semiconductor laser for both a light source and a detector is described. A method for enhancing the depth discrimination of a confocal microscope is also described, in which a semiconductor laser is driven by the current below the threshold. Experimental results are shown to verify the effectiveness of the proposed microscope.
