Apparatus and method for alignment of fixed communication laser stations
Patent
·
OSTI ID:6987644
This patent describes an apparatus for alignment of a laser beam transmitted from a fixed laser transmitting-receiving station so that the transmitted beam can be made parallel to a beam received by the same station. It comprises: a mounting plate; a laser source attached to the mounting plate by a means preventing relative movement between the laser source and the mounting plate; a lens attached to the mounting plate by a means preventing relative movement between the lens and the mounting plate, with the lens oriented so that its centerline is parallel to and centered upon a beam generated by the laser source, and with the lens projecting from one face to the mounting plate; a support surface which forms part of the outside surface of the laser transmitting-receiving station. The support surface being rigidly attached to a station support means, and the support surface including a clearance hole through which the lens penetrates, a pivot means attached to the support surface and engaging the lens, and at least two threaded through holes; and at least two threaded rods each with one end screwed into the threaded holes in the support surface and the other end projecting toward and contacting the mounting plate, with the end within the threaded hole containing a means by which to turn the threaded rod. The turning means being accessible from outside the laser transmitting-receiving station.
