1. An optical zoom probe comprising:
an aperture adjuster which adjusts an aperture through which light which is transmitted by a light transmitter propagates; and a focus adjuster which focuses light that propagates through the aperture and which comprises a first liquid lens and a second liquid lens, for each of which respective curvatures are independently controllable so as to adjust a respective focal length, wherein at least one of the first and second liquid lenses further comprises a transparent film which has a curved surface and within which a through hole is formable, and in a near scanning mode, the curved surface of the transparent film acts as a lens surface, and in a nearest scanning mode, the curved surface of the transparent film does not act as the lens surface.
