Abstract
A simple method is demonstrated for measuring the cell gap of reflective twisted nematic (RTN) liquid crystal (LC) cells. This method utilizes a single laser beam and crossed-polarizer configuration such that Fabry-Perot effect and surface reflection are eliminated. Experimental results agree well with theory.
