Laser Guide Star Projection Subunit.
Demcon and TNO have developed a groundbreaking Laser Projection Subunit (LPS) system. This system is designed to generate an artificial star in the mesosphere as a reference for the telescope’s adaptive optics. It uses 589 nm laser to generate an artificial star in the mesosphere. The LPS system can handle azimuth positions and temperature variations of the telescope, which is crucial for accurate observations. We can also support other telescope systems with this advanced technology, enhancing their adaptive optics and overcoming the effects of atmospheric turbulence. This marks a significant step forward in improving astronomical observations. The system are being commisioned at the ESO Very Large Telescope (VLT) and Extremely Large Telescope (ELT) observatories.
fine steering mirror.
Precision laser beam steering determines the quality and bandwidth of satellite laser communications for fast and secure internet and data traffic. For this purpose, the Fine Steering Mirror (FSM) has been designed. We developed a TNO design into a prototype that is a space-compatible and light-weight and has a lower power consumption. We can manufacture FSMs in large numbers.
fast Wave Front Sensor.
Demcon Focal’s expertise in high-speed and high-accuracy wavefront sensing was instrumental in creating a custom Shack Hartmann wavefront sensor. This sensor, equipped with advanced FPGA IP cores, enabled real-time wavefront correction at 10kHz with minimal latency, ensuring robust and reliable communication links between Earth and space.
Shack Hartmann wavefront sensor technology can benefit a wide range of industries due to its precision and versatility.
