Abstract: A handheld imaging probe for performing optical coherence tomography is disclosed. The handheld imaging probe includes a lens tube and a housing. The lens tube contains an objective lens and a polycarbonate sheet. The polycarbonate sheet provides a bio-safe contact with a tissue sample to be examined. The housing, which is connected to the lens tube, contains a micromirror for directing a laser beam to irradiate the tissue sample via the objective lens and the polycarbonate sheet.
