| Title: |
Optical System for Creating Colored Fields of Light and Components Therefor |
| Abstract: |
Units for projection of profiled images and for floodlighting suffer from a
tradeoff between the quality of the illuminated field and efficiency. The
hue, saturation, and intensity must be continuously controllable, and the
quality of the illuminated field must be even. According to the invention
the optical components have been refined according to a general principle
which enables the use of efficient elliptical reflectors without a
reduction in quality for both purposes. Each color is controlled by
relatively moveable filters having a comblike structure in which the
design of the individual teeth compensates for the interaction of the many
variables. The intensity is controlled by mechanical dimmers which are
designed according to the same principles. This construction will also
improve the quality of condenser type projection systems.
