Multi-color Industrial Grade DLP-projection STAR-07 RGB



STAR‑07 is a high-performance pattern projector based upon the Texas Instruments DLP micro mirror device 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 1.024 x 768 mirrors. These bi-stable mirrors flip into opposite tilt positions within microseconds to generate the desired patterns. STAR‑07 provides precise high‑speed control for each individual mirror enabling outstanding flexibility and pattern frame rates of the projection output. The projector is equipped with a high‑power LED light source that is the key for the compact and rugged design of the device.

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 Architecture:

The central control unit of STAR‑07 is USB2.0 connected and realizes pattern upload, display and synchronization.   An integrated trigger facility supports selectable voltage levels and is software programmable. The digital driver for   the LED light source gives convenient access to power setting and temperature reading for thermal management.

System Control

The ViALUX ALP‑4.2 Controller Suite is the central programming tool and provides all necessary functionality for product development. Sequences of patterns are uploaded from PC to the on‑board memory via USB 2.0 transfer with lossless compression. 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; even higher frame rates up to 50 kHz can be achieved by partial updates of the DLP micro mirror array. Multiple STAR‑07 devices can be run in parallel, conveniently controlled from the same application program and precisely synchronized by the trigger facility.

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. For detailed information on absolute maximum ratings refer to the LED type printed on the device label and the corresponding data sheets of the LED manufacturer.
