ABSTRACT:
One embodiment disclosed relates to a method for calibrating an array of light-modulating elements. The method includes illuminating the array of elements, modulating an intensity of light diffracted by the elements over a modulation range, and measuring the modulated light intensity from each element of the array using a linear detector. Other embodiments disclosed relate to an apparatus and system for calibrating an array of light-modulating elements. The apparatus includes a light source for illuminating the array of elements and a linear detector for measuring light intensities at points along a line segment. The apparatus is configured so that modulated light from each of the elements impinges upon a different point of the line segment. The system includes means for modulating an intensity of light diffracted by the elements over a modulation range and a detector for measuring the modulated light intensity from each element of the array.
