Disposal Information

This equipment has required the extraction and use of natural resources for its production. It may contain hazardous substances for health
and environment. In order to avoid the dissemination of those substances in the environment and to diminish the pressure on natural
resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle most of the materials of your
end of life equipment in a sound way.

The crossed-out wheeled bin symbol invites you to use those systems. If you need more information on the collection, reuse and recycling
systems, please contact your local or regional waste administrator. You can also contact us for more information on the environmental
performances of our products.

Guarantee and Compensation

Barco provides a guarantee relating to perfect manufacturing as part of the legally stipulated terms of guarantee. On receipt, the purchaser
must immediately inspect all delivered goods for damage incurred during transport, as well as for material and manufacturing faults Barco
must be informed immediately in writing of any complaints.

The period of guarantee begins on the date of transfer of risks, in the case of special systems and software on the date of commissioning,
at latest 30 days after the transfer of risks. In the event of justified notice of complaint, Barco can repair the fault or provide a replacement
at its own discretion within an appropriate period. If this measure proves to be impossible or unsuccessful, the purchaser can demand a
reduction in the purchase price or cancellation of the contract. All other claims, in particular those relating to compensation for direct or
indirect damage, and also damage attributed to the operation of software as well as to other services provided by Barco, being a component
of the system or independent service, will be deemed invalid provided the damage is not proven to be attributed to the absence of properties
guaranteed in writing or due to the intent or gross negligence or part of Barco.

If the purchaser or a third party carries out modifications or repairs on goods delivered by Barco, or if the goods are handled incorrectly,
in particular if the systems are commissioned operated incorrectly or if, after the transfer of risks, the goods are subject to influences not
agreed upon in the contract, all guarantee claims of the purchaser will be rendered invalid. Not included in the guarantee coverage are
system failures which are attributed to programs or special electronic circuitry provided by the purchaser, e.g. interfaces. Normal wear as
well as normal maintenance are not subject to the guarantee provided by Barco either.

Overview

• Safety Instructions

1.1 Safety Instructions

WARNING: The Laser Diode Array Tool™ or LDAT™ can only be serviced by a qualified Barco Technician,

other servicing may result in hazardous radiation exposure.

Notice on Safety

The LDAT™ is built in accordance with the requirements of the international safety standards EN60950, UL 1950 and CSA C22.2
No.950, which are the safety standards of information technology equipment including electrical business equipment. These safety
standards impose important requirements on the use of safety critical components, materials and isolation, in order to protect the
user or operator against risk of electric shock and energy hazard, and having access to live parts. Safety standards also impose
limits to the internal and external temperature rises, radiation levels, mechanical stability and strength, enclosure construction and
protection against the risk of fire. Simulated single fault condition testing ensures the safety of the equipment to the user even when
the equipment’s normal operation fails.

Operation Instructions

Before operating this equipment please read this manual thoroughly, and retain it for future reference.

Installation and Service Instructions

Installation and Service adjustments should only be performed by qualified BARCO personnel or by authorized BARCO service
dealers.

WARNING: Use of controls or adjustments or performance of procedures other than those specified in this

manual may result in hazardous radiation exposure.

2. INTRODUCTION

2.1 LDAT™

WhyusetheLDAT™?

In multi-channel projection displays, externally generated test pattern grids are generally used
geometric (electrical) alignment of the many display channels. These test patterns are designed to represent the location of signifi-
cant 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.

as references for mechanical and

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 5x6 Laser Array, 5 laser light sources are config­ured as Outline Laser, these mark 4 corners + 1 centre point of the Angular Field Of View

1. In a multi channel setup, each display channel will cover a specific field of the large screen (e.g. a dome simulator setup). This field is called the Angular Field Of View.

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 5x6 Laser Array, 25 light sources are used to
mark the Warp Test Pattern.
