STAR-07 RGB
MULTI-COLOR INDUSTRIAL PATTERN PROJECTION
STAR-07 RGB is a high performance DLP® projector based upon the
Texas Instruments micromirror technology and designed to serve in
demanding industrial applications. Widely used in multimedia and
digital cinema since more than one decade, the well proven DLP
technology has become an important tool for industrial solutions as
well. The heart of the STAR-07 projector is a 0.7” DLP chip that
consists of an array of 1024x768 mirrors. These bi-stable mirrors flip into opposite tilt
positions within microseconds to generate the desired patterns. STAR-07 RGB provides
precise high-speed control for each individual mirror enabling outstanding flexibility and
pattern frame rates of the projection output.
The STAR-07 RGB projector is equipped with three high-power LED light sources and an
integrated cooling system. Typical use cases are 3D volumetric display, 3D measurement,
augmented reality applications, and machine vision illumination. Beyond that, new
emerging applications are well supported by an open SDK interface. STAR-07 RGB comes
with two lens options, the standard projection lens with zoom capability and a wide angle
lens with fixed focal length.
SYSTEM CONTROL
The ViALUX ALP-4.2 Controller Suite is the central programming tool and provides all
necessary features for advanced product development. Sequences of patterns are
uploaded from PC to the on-board memory via USB2.0 transfer with lossless compression.
The STAR-07 RGB is USB2.0 connected and realizes pattern upload, display, and
synchronization. Three individual digital drivers for the three LED light sources give
convenient access to power setting and temperature reading for thermal management of
each single LED. In addition, each LED is gated by a programmable high-speed control line.
An integrated trigger facility supports selectable voltage levels for external master or slave
modes of control.
Active Cooling
The properties of the display sequences, e.g. bit depth, picture time, trigger mode, repetitions
can be freely defined to meet the respective application requirements. The ALP-4.2 firmware
streams patterns from on-board SDRAM memory to the DLP7000 micro mirror array where
the input pattern is one-to-one mapped to the mirrors. The patterns are updated in the global
reset mode; that means all mirrors are switching simultaneously within a few microseconds.
Grey value patterns are generated by controlled ON-time for each mirror yielding exact grey
value linearity. The maximum global array switching rate is 22 727 fps. Multiple STAR-07
RGB devices can be run in parallel, conveniently controlled from the same application
program and precisely synchronized by the trigger facility. The ALP-4.2 API is well proven
and the DLL is compatible to C++, VBasic, .NET, LabView, and other development platforms.
Microsoft® operating systems are supported up to the most recent Windows® versions both,
32-bit and 64-bit. The ALP-4 USB2.0 driver is robust, validated, UIF compliant and 24/7
proven in industrial and medical use cases.
OPTICAL AND THERMAL DESIGN
The red, green, and blue light output of each LED is combined and fed
into the homogenizer (light tunnel) by means of a dichroic mirror system.
The output color of STAR-07 can be RGB switched with the full frame
rate. A common copper heat sink with an active cooler is included for the
thermal management of the LED light sources. The temperature
monitoring facility of ALP-4.2 provides all the information needed to
guarantee safe LED operation within the specified limits.
