| Title: |
Followspot Parameter Feedback |
| Abstract: |
Apparatus for providing the operator of a light projector suitable for
performance lighting and capable of beam azimuth and elevation control
with data as to the current values of the projector's adjustable
parameters. Current azimuth and elevation data is presented both visually,
by means of a viewfinder mounted on the projector, and numerically, by
means of digital displays. Alternatively, visual feedback may be provided
with an imaging device having a field of view substantially the same as
the beam mounted at the projector coupled to a display located at a
location remote from the projector. A drive for remotely controlling the
light projector in azimuth and elevation is then provided.
