 EFFECT MODULES
All modules include necessary drive electronics and cabling as required. Items 'A' through 'G' mount directly to the 4 Position Section (section II.A) or dovetail rail Effect Module Mount (section I.D.5).
A. Scanner (Hi-res X-Y-I) (Hi-res X-Y)
The 'business end" of most laser display systems, Scanner (Hi-res X-Y-I) includes two closed-loop (feedback) scanners for horizontal and vertical deflection of a laser beam, while a third scanner provides intensity modulation ("blanking"). This arrangement is usually necessary for logos, animation, words, etc. Scanner (Hi-res X-Y) is without the intensity scanner, and is often used when blanking is not necessary, or is provided by other means, such as a PC-AOM (see I.D.6).
B. Scanner (Lo-res X-Y)
Two open-loop (non-feedback) scanners provide lower resolution graphics, without blanking. Useful for scanning into atmosphere, and/or where image quality is less critical.
C. Scanner ("Fan")
A single, low resolution device draws a line, creating a "fan" of light through the air. A prism may be incorporated to split the beam into its component colors.
D. Scanner ("Cone")
A high speed precision motor draws a circle, creating a "cone" or "tunnel" of light.
E. Diffraction Wheel ("Lumia")
Slowly rotating wheels mounted on a motor produce cloudy, web-like interference patterns or "starburst" effects on screen. Variety of wheels available.
F. Beam Positioner
Precisely positions beam in any fixed direction. Units may be stacked up to four high to create a
compact beam-splitter assembly allowing simultaneous beams with fully independent adjustment from
a single projector aperture.
G. Fiber-Optic Remote
Any of the above modules may be placed in a remote location, with the laser light brought to it through a fiber optic cable mounted in a precision positioner. The remote locations should still be viewable by an operator, according to most safety regulations. Yoke mounts with C-clamps are included to facilitate remote mounting. Specify cable length and type (300' [91 m] maximum recommended). Two types of fiber are offered - a commercial grade, 100 micron core, and a high perfomance grade 50 micron core. The high performance grade provides superior laser power handling capability, and improved effeciency and output beam characteristics.
Fiber-Optic Coupler
This fiber optic coupler attaches to the four position section. It allows adjustment for precise positioning of the beam into the fiber.
H. Color Box
Dichroic color filters are mounted on small, open-loop scanners, allowing rapid color changes. This
module mounts under one of the above individual Effect Modules, or ahead of all Projector Sections,
on a Dovetail Mount, for use as a system color selector.
I. Direct Remote "Fan"
Similar to 'C above, but yoke mounted with theater type "barndoors" attached. May he hung overhead or set on the floor. The laser beam is then positioned to strike it, using a Beam Positioner module. All direct remotes include 100' (30m) of cable.
J. Direct Remote "Cone"
Similar to 'D' above, but configured and used as is 'I'.
K. Direct Remote "Lumia"
Similar to 'E' above, but configured and used as is 'I'.
L. Bounce Mirror
High quality, first surface mirrors are yoke mounted to C-clamps or floor stands to reflect or "bounce" laser bearns around a space. Two sizes, 4" or 8", the larger being for longer throws. Both are available with precision adjustment.
M. Diffraction Mirror
Similar to 'L' above, but a diffraction grating replaces the mirror element. An incoming beam striking this is split up into an array of beams, revealing any colors that may be present. Both single axis (linear) and multi-axis (starburst) available. 4" size only.
