| Title: |
Apparatus for Steering a Light Beam Using Two Mirrors Having Only One Mirror Moved |
| Abstract: |
Improvements are disclosed to lighting fixtures, support structures,
interconnecting cabling, and other subjects. An improved method allows
precise control of the beams of high power, long throw followspots by
means of a steering mirror motorized in two axes. The beam is first
directed upwards from the followspot by a first mirror to the steering
mirror above. The range of elevations through which the beam can be
steered is increased by displacing the steering mirror relative to the
first mirror such that the portion of the beam between them is not
vertical.
