Light beam collimator particularly suitable for a densely packed array

摘要

A method and apparatus for controlled displacement, rotation and deformation of parts of a fiber optic collimator so as to provide multiple degrees of adjustment freedom that are decoupled one from another, for adjusting the path of a light beam, comprising: an output elongate hollow node for passing a light beam therethrough and towards a lens, and an elongate hollow base node having separate top and bottom parts connected to each other by opposed ends of a plurality of flexible rods that restrict the relative movement between the top and bottom parts of the base node to substantially only translational parallel movement. Opposed portions of the top and bottom parts of the base node each include a respective screw and an opposed slanted surface, which upon interaction, develop a shearing force which is applied to the top and bottom parts of the base node and cause a translational parallel relative movement therebetween.

1. An apparatus for controlling the position of a light beam relative to a lens, comprising:
an elongate hollow output node having an upper portion and a bottom portion for passing a light beam therethrough, the upper portion providing the light beam along a longitudinal axis of the output node towards a lens; and an elongate hollow base node having separate top and bottom parts connected to each other along a longitudinal axis of the base node by opposed ends of a plurality of flexible rods that restrict the relative movement between the top and bottom parts of the base node to substantially only translational parallel movement, the top part of the base node being coupled to the bottom portion of the output node and the bottom part of the base node being coupled to receive therein the light beam; wherein for adjusting the translational parallel movement between the top and bottom parts of the base node, opposed portions of the bottom part of the base node each include a respective screw that adjustably extends in a direction parallel to the longitudinal axis of the base node, and opposed portions of the top part of the base node each include a respective slanted surface that opposes a screw in a correspondingly positioned opposed portion of the bottom part of the base node, so that extension of one screw in the bottom part of the base node in combination with retraction of another screw in the bottom part of the base node, establishes a shearing force that results in precisely controlled translational parallel relative movement between the top and bottom parts of the base node.
