Optical Coherence Microscopy (OCM) is a bio-medical low coherence interferometric imaging technique that has
become a topic of active research because of its ability to provide accurate, non-invasive cross-sectional images of
biological tissue with much greater resolution than the current common technique ultrasound. OCM is a derivative of
Optical Coherence Tomography (OCT) that enables greater resolution imposed by the implementation of an optical
confocal design involving high numerical aperture (NA) focusing in the sample. The primary setback of OCM, however
is the depth dependence of the lateral resolution obtained that arises from the smaller depth of focus of the high NA
beam. We propose to overcome this limitation using a dynamic focusing lens design that can achieve quasi-invariant
lateral resolution up to 1.5mm depth of skin tissue.
