  • Tunable optical device, tunable liquid crystal lens assembly and imaging system using same
    Patent number: 10631715
    Abstract: There is disclosed an imaging system for use in imaging a sample. The imaging system comprising a light source and a light detector. A probe optically coupled to the imaging assembly. The probe being configured to, during use, direct light from the light source to a focal point to illuminate the sample, and from the focal point to the light detector. 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.
