In an exemplary display system adapted to display an image to an observer using a display where at least one of the display and observer is subjected to physical vibration referred to as jitter, accelerometers are mounted to elements subject to jitter and associated with the observer. A processing system uses acceleration measurements from the accelerometers to calculate an x-axis and y-axis jitter correction factors based on a comparison of the acceleration measurements, and generates a video output in which the visual information is displaced along the x-axis and y-axis based on the x-axis and y-axis jitter correction factors so that an image corresponding to the video output shown on the display appears to the observer as not having jitter.

Stabilization of the effects of jitter on a displayed image

A cell in one example comprises an alkali metal and a coating of parylene on an interior surface of the cell. In one implementation, the alkali metal may be an optically pumped gaseous phase of an alkali metal. The parylene coating minimizes interaction of the excited state of the alkali metal, increases lifetime of the excited state, and minimizes interaction of nuclear spin states with the cell walls.

Micro-cell for NMR gyroscope

In an embodiment of a ring laser gyroscope, a hollow bandgap fiber is filled with a gas or material that will generate laser beams within the fiber upon being excited by an energy source. A detector coupled to the fiber detects a standing wave pattern within the fiber, wherein changes in the detected standing wave pattern indicates a corresponding change in the orientation of the fiber.
