Light beam framing system with merged shutter blades

摘要

The present invention relates to a framing system for shaping a light beam. The framing system comprises a frame support comprising a number of shutter blades surrounding said light beam and a number of actuators adapted to move said shutter blades in and out of said light beam. The shutter blades form a merged pile, where part of a first shutter blade is in placed over a part of a second shutter blade and where another part is placed below a part of a third shutter blade. A first actuator rotates at least one of said shutter blades in relation to a first rotational point and a second actuator moves the first rotational point in relation to said light beam. The present invention relates further to a method of shaping a light beam comprising the steps of rotating a shutter blade around a first rotation point using a first actuator and moving the first rotation point in relation to the light beam using a second actuator.
