Abstract: Described embodiments provide for an optical communications assembly or other optical assembly in which the post-dispersion optical signals are controlled in dispersive and non-dispersive directions. In one embodiment, the assembly includes an optical signal collimator configured to emit an optical signal based on an input communication signal. In addition, the assembly includes a dispersive device that receives the optical signal and disperses multiple wavelength channels of the optical signal in a dispersive direction. The assembly further includes a first light-directing device configured to control the dispersion of the multiple wavelength channels in the non-dispersive direction. A second light-directing device is provided to control dispersion in the dispersive direction.

Abstract: A system and method for the modulation of light propagating along an optical path, for example the optical path in a projection display system. As light in the optical path travels from a light source to a display screen, it is shaped and modulated by the various components of the optical path so that the intended visual image appears on the display screen. In accordance with the present invention, a mirror disposed proximate the optical path is operable to be selectively inserted and removed from the optical path to alternately direct the light from one portion of the optical path to another, or to a light dump where it can be absorbed such that the associated heat energy may be properly dissipated. In a preferred embodiment, the mirror is a fold mirror mounted at a stop of the system to fold the light beam approximately 90 degrees when the mirror is inserted in the optical path.

Abstract: Method for designing color display sequences in a display system using rapidly switching light sources. A preferred embodiment comprises determining a number of bit segments in a frame time, determining a color sequence, and specifying a bit sequence from the color sequence. The bits in the bit sequence are delineated by a switching of a rapidly switching light source or a state change of a light modulator. The use of the rapidly switching light source can permit the specification of bits that are shorter than a minimum duration of a state change of the light modulator and the possible elimination of a segmented color filter that can enable adjustments to the color point of the display system to meet changing operating conditions.

Abstract: System and method for the implementation of a transition zone associated with an actuator of an optical device in a display system. A preferred embodiment comprises determining a sub-frame transition time, initiating a sub-frame transition to coincide with a start of a spoke state of a color filter if the sub-frame transition time is less than or substantially equal to a duration of the spoke state, and spanning the sub-frame transition over the spoke state and a color state of the color filter if the sub-frame transition time is greater than the duration. The overlapping of at least a portion of the sub-frame transition with the duration of the spoke state can reduce the impact of the sub-frame transition on the image quality of the display system, since the display system is not displaying images during the spoke state.
