摘要：

Generally speaking, the output brightness of an illuminator is varied by chopping an output light beam such that the beam is alternately interrupted and unhindered. An interrupter can be rapidly moved into and out of the transmission path of a light beam. The brightness of the light beam received at a site will be attenuated based on the amount of time per cycle the light beam remains obstructed versus unhindered.
