Industrial grade DLP® projection
STAR-07

Typical use cases are machine vision illumination, 3D scanning, industrial exposure, and additive manufacturing. Beyond that, new emerging applications are well supported by an open SDK interface. STAR‑07 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.
