Latest Patents

Mercer’s latest patent, titled “Common Path Point Diffraction Interferometer Using Liquid Crystal Phase,” describes a unique design employing dyed, parallel nematic liquid crystals surrounding an optically transparent microsphere. This innovative setup allows coherent, collimated, and polarized light to be focused on the microsphere, creating a spherical wavefront reference beam while manipulating the object beam through attenuated light. An interferogram is formed as these beams interact, and subsequent computer analysis determines the wavefront of the object beam.

Her second patent, “Phase-Stepping Fiber-Optic Projected Fringe System for Surface,” presents a robust projected fringe interferometer designed to measure object topography. This system operates by periodically stepping the phase angle between two light beams, enabling precise recording and analysis of fringe patterns. The device incorporates photodetectors and a closed-loop control system, which ensures accurate maintenance of the phase relationship, ultimately allowing for an accurate phase map of flat surfaces.
