RSAA Laser Communication Program

The RSAA Laser Communication Program is a translational research effort that adapts cutting-edge astronomy technologies for space and terrestrial communication applications. Our work spans adaptive optics, high-power lasers, quantum and classical optical communication, advanced detectors, and large telescope systems. Students joining the program will be embedded in a fast-paced, collaborative research environment working on nationally and internationally significant projects.

Atmospheric turbulence fundamentally limits the performance of large optical telescopes and laser communication systems. This project focuses on measuring and characterising turbulence above both Mount Stromlo and Siding Spring Observatories to inform the design and operation of adaptive optics and optical communication systems.

Project Focus

Students will help commission and operate the Ring Image Next Generation Scintillation Sensor (RINGSS), a newly developed atmospheric turbulence profiling instrument, and analyse the resulting data to produce site statistics.

Activities May Include

• Commissioning and operation of the RINGSS instrument including remote deployment and for daytime operation
• Collecting turbulence measurements under a range of atmospheric conditions
• Analysing turbulence strength, altitude profiles, and temporal evolution
• Using results to inform adaptive optics and optical communication system design

Outcomes

• A validated turbulence dataset for Mount Stromlo
• Improved models for adaptive optics and laser communication performance
• Direct impact on current and future ground-based optical systems

Skills & Backgrounds

• Adaptive optics and atmospheric compensation
• Optical system design
• Detectors and high-speed electronics
• Signal processing and control software
• Satellite tracking and ground station operations
• Turbulence modelling, profiling, and data analysis
