Abstract
A light modulator incorporates a polarization sensitive prism and a novel MEMS ribbon device to impart a relative phase shift to polarization components of an incident light beam. A linear array of phase shifting elements in the MEMS device creates a linear image which is scanned to form a two dimensional scene. Alternatively the deflection of each cantilever in a linear array of atomic force microscope cantilevers may be measured simultaneously.
Claims1
A light modulator comprising:
- a polarizing prism that splits a light beam into different paths corresponding to polarization components of the light;
- and,
- a microelectromechanical device that imparts a relative phase shift to the light in the paths prior to recombination of the light in the polarizing prism.
Dependencies are inferred from the claim text.
