Abstract:
An SBS cell ( ) for use in combination with a laser system ( ) on a mobile platform. The SBS cell ( ) includes inner and outer tubes ( ) that define inner and outer chambers ( ). The inner tube ( ) is completely filled with an SBS fluid ( ) and the outer tube ( ) is filled to a level that is above the fill hole ( ) of the inner tube ( ). The outer tube ( ) is sized to trap enough air to provide a compressible volume for cell fluid expansion from temperature changes in the laser environment. The SBS cell ( ) is filled in an upside-down position, and the cell ( ) is rotated 180Â to its operating position. In this position, the fill hole ( ) is pointed downward, and since the air bubbles float to the top, the distance between the inner tube fill hole ( ) and the trapped air is sufficient enough to prevent air bubbles from migrating to the fill hole ( ) and entering the inner tube ( ). Without air bubbles within the inner tube ( ), fluid sloshing from vibrations does not affect the optical beam.
