InfoComm 2019: Digital Projection previews Satellite Modular Laser System

Digital Projection is using this year’s InfoComm to give a technology preview of its latest innovation – the Satellite Modular Laser System (MLS).

Satellite MLS offers a small number of simple building blocks that will allow users to address a wide range of applications, from single projector installs to complex, multi-channel domes, caves and simulators.

The keystone of this new system is the separation of the light source, with its associated power and thermal management, to a remote location, which enables a small, compact projection ‘Head’ that only contains the minimal optical and video processing.

The projector ‘Head’ is fundamentally compact, quiet, light-weight and consumes very little power. This offers huge benefits at every stage of a system design, from transportation and installation to serviceability and lifespan. By separating the projection Head from the light source and linking the two by robust and flexible fibre-optic cables up to 100m long, it offers the installer many more options, particularly where space and access are restricted.

The Satellite MLS will be developed around WUXGA, Native 4K and 8K resolutions and will also incorporate Digital Projection’s ‘MultiView’ technology.

Given the modular design of the system, there can be a one-to-many, or many-to-one relationship between the light sources and the projection Heads.

In a one-to-many relationship, a single 10,000 lumen light source can feed multiple projection Heads, equally splitting – and precisely controlling – the luminance of each image through the life of the system.

In a many-to-one relationship, multiple 10,000 lumen Satellite MLS light modules can be combined to feed a single, ultra-compact projection Head, resulting in a lumens-per-kilogram ratio that far surpasses anything that precedes it.

In addition to the many logistical, installation and performance benefits of Satellite MLS – including modularity, small size, low noise and low power consumption – users will benefit from enhanced system longevity with reduced need for servicing.

Each projection Head is designed with a closed-loop cooling system, essentially sealing all of the critical optical components from ingress of contaminants. A further benefit of the reduced thermal dissipation and small size is that supplementary environmental enclosures become easier to design and manufacture, further reducing total system costs.
