The probe having a tunable liquid crystal lens (TLCL) assembly comprising at least one pair of TLCLs, the TLCLs of the pair being superposed to one another, a gradient-index (GRIN) lens assembly having a base being optically connected to the TLCL assembly, and a tip opposite to the base. The focal point being at a working distance from the tip. The working distance being adjustable relative to the tip by tuning each TLCL of the TLCL assembly during use.
