POLARIZATION-SELECTIVE VARIFOCAL LIQUID LENS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240319509 titled 'POLARIZATION-SELECTIVE VARIFOCAL LIQUID LENS
Simplified Explanation:
The varifocal liquid lens described in the patent application consists of a body filled with two different fluids separated by a variable curvature interface. The refractive index and optical power of the lens depend on the polarization of the impinging light, with one of the fluids being birefringent. This allows for a variable optical power for different polarizations of light.

Original Abstract Submitted
a varifocal liquid lens includes a body filled with two different fluids separated by an interface of a variable curvature across a clear aperture of the varifocal liquid lens. at least one of the first or second fluids is birefringent, such that a refractive index difference between the first and second fluids and resulting optical power of the varifocal liquid lens is dependent on polarization of impinging light. at a first light polarization, the first and second fluids may be matched in refractive index, while at a second, orthogonal light polarization, the first and second fluids may be mismatched in refractive index, whereby the first interface between the first and second fluids may have a variable, non-zero optical power for the second polarization while having a substantially non-variable, zero optical power for the first polarization of light.
