Abstract
An image projector includes a digital micro device (DMD) spatial light modulator and a rotatable actuator. The rotatable actuator is disposed in a path of light reflected from the spatial light modulator. The rotatable actuator includes a first region and a second region. The first region is tilted at a first non-normal angle with respect to an axis of rotation of the rotatable actuator. The second region is tilted at a second non-normal angle with respect to the axis of rotation of the rotatable actuator. Light reflected by the spatial light modulator and passing through the first region is displaced one pixel relative to light reflected by the spatial light modulator and passing through the second region.
