  • Patent number: 6266176
    Abstract: The present invention includes optical interconnection devices and optical interconnection systems. The invention also includes machines and instruments using those aspects of the invention. The invention may also be used to upgrade, repair, or retrofit existing machines or instruments, using methods and components known in the art. An optical interconnection device of the present invention utilizes a multiple-pass optical cell. This approach differs from previous approaches in that spatial light modulators are used in a White cell device or other multiple-pass optical configuration. In a spatial light modulator, each individual element typically only has two or three variations used to direct the light. Therefore, precise calibration is not needed. The light simply needs to be directed towards the appropriate arm of the optical cell, which utilizes a self-correcting mirror in order to direct a light stream to the next desired location in the system.
