ABSTRACT:
A method and apparatus for adjusting spatial light modulators in an imaging system. The apparatus includes several screws, plungers and pins connecting to a housing. When the screws and plungers are adjusted, the device held by the housing is manipulated along the x, y and z axes, allowing the device to be focused and aligned. If multiple modulators are involved, they can also be converged. The method includes the steps of mounting the devices in adjustable sockets, aligning each device, focusing each device and then positioning images from each device to converge with images from other devices.
