PROCEDIMIENTO Y APARATO PARA ALINEAR LA PROPAGACION DE UN HAZ LUMINOSO |
摘要 |
<p>An optical rotary joint has a first pair of light beam expanding graded index (GRIN) of refraction lenses coupled to ends of a first pair of lightguide fibers for coupling signals through the rotary joint interface in a first path which is coaxial with the axis of rotation in the interface. A second pair of lightguide fibers are coupled to a second pair of GRIN lenses off-axis and of much smaller diameter than the lenses of the first pair. Prisms couple signals between the off-axis lenses and a second path across the interface and which is also coaxial with the axis of rotation. Also shown is a method for compensating for lens irregularities.</p> |
