Advanced high performance
acousto-optical scanning system is able to project text or graphic dynamic
information or a laser film on a large screen. The instrument is specially
designed for the high power lasers operating in visible spectral range
(from blue to red). The heart of the LSS is original two-coordinate
acousto-optical deflector based on paratellurite single crystal.
The system is intended for indoor/outdoor operations with the following
application aim: in advertisements and show business entertainment.
The LSS consists of an integrated acousto-optical system, XY external
driver and PC interface card. The integrated acousto-optical system
consists of input beam-forming optics, XY AO deflectors, in intermediate
objective and projection objective with zoom capability.
The laser animation can be created by means of the specially designed
computer program - film editor which is able to create and to demonstrate
the frame sequences of arbitrary size. Any frame can be created either
by PCX or GIF picture importing, or by means of the internal vector
graphic editor. DOS text files can also be imported. The film editor
allows to create a very smooth and continuous animation as well as different
text effects. The laser animation can be demonstrated by means of a
special plaing program. During the demonstration it is possible to vary
its speed and to fit options, e.g. output picture turning and mirror
reflections. |
