Abstract
A six-axis attachment mechanism for aligning a spatial light modulator (106) within a display system. An attachment plate (100) has one or more pins (104) extending therefrom. A socket plate (108) onto which a spatial light modulator (106) is attached slides over the pins (104). The modulator is then positioned to optically align it with the remainder of the display system. As the modulator is held in alignment, a washer (110) is slid onto the pin (104) and is bonded to both the pin (104) and to the socket plate (108). Washers (110) are typically transparent to enable the use of an optically cured adhesive. Glass washers (110) allow ultraviolet radiation to reach the adhesive through the glass washer (110).
