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.

La présente invention a trait à un modulateur de lumière incorporant un prisme sensible à la polarisation et un nouveau dispositif de ruban à microsystème électromécanique pour imprimer un déphasage relatif aux composantes de polarisation d'un faisceau lumineux incident. Une matrice linéaire d'éléments de déphasage dans le dispositif à microsystème électromécanique crée une image linéaire qui est balayée pour former une scène bidimensionnelle. En variante, la déviation de chaque cantilever dans la matrice linéaire des cantilevers de microscope de force atomique peut être mesurée simultanément.
