INTRODUCTION
2.1 LDAT™
WhyusetheLDAT™?
In multi-channel projection displays, externally generated test pattern grids
are generally used as references for mechanical and geometric (electrical)
alignment of the many display channels. These test patterns are designed to
represent the location of significant landmarks that may be pre-calculated
positions, according to the type of screen (flat, curved, front, rear, etc.),
eye-points and position of the projectors.
Many solutions exist to visualize the pre-calculated points to guide display
alignment: one can mark “invisible” dots using UV-paint, one can use a slide-
projector to project these points, one can install small LED’s or fiber optic
strands in the screen surface for
example. None of these solutions is ideal: they can’t be used on all types of
screens, they require a complicated setup which may include direct access to
the screen surface, several are inaccurate and expensive to correct, and many
can only be used in a dark
environment.
The ‘laser arrays’ provide a method and device for generating a test pattern
grid for being used as reference for aligning display channels without having
the disadvantages of the solutions mentioned above.
The test pattern generator has a surface, each light source being moveably
fixed on the surface and being adjustable such that a direction of light
emitted from each light source can be set for directing light from the light
source onto the screen.
2.2 Outline Lasers
Why use Outline Lasers?
Some Laser Light sources of the Laser Array are configured as Outline Lasers.
These Outline Lasers will mark the Outline corners of the desired projection
area on the screen.
The Outline Lasers are the reference points for the mechanical alignment of
the projectors.
This illustration shows a single display channel for a Dome Simulator Setup
with a 5×6 Laser Array, 5 laser light sources are configured as Outline Laser,
these mark 4 corners + 1 centre point of the Angular Field Of View1
2.3 Warp Lasers
Why use Warp Lasers?
The remaining laser light sources will be used as Warp Lasers.
These Warp Lasers will mark the geometric test pattern that is used for
geometric (electrical) alignment of the projector.
This illustration shows a single display channel for a Dome Simulator Setup
with a 5×6 Laser Array, 25 light sources are used to mark the Warp Test
Pattern.
