1. An automated multiparameter luminaire comprising:
a light source generating a light beam with a central axis;
a plurality of light modulators;
wherein one of the light modulators is a combined hot mirror and light diffuser
which is articulated to engage the light beam and disengage the light beam; and
while the hot mirror engages the light beam, the articulation is oscillated over a range of motion that maintains full engagement
of the hot mirror in the beam while varying its position within the light beam.
