Bologna Integration Hall Prepares for MORFEO Adaptive Optics Assembly
The Bologna Integration Hall is being completed as a joint centre of excellence established by INAF and the University of Bologna to support MORFEO’s integration and testing activities, the University of Bologna reported on October 6. Designed as an adaptive optics system for the European Southern Observatory’s Extremely Large Telescope (ELT) in Chile’s Atacama Desert, MORFEO will compensate in real time for atmospheric turbulence to maximize the potential of the telescope’s 39-metre-diameter primary mirror.
Infrastructure Development at the Bologna Research Division
The integration facility is located at the ARIC Research Division, emerging from a strategic partnership between the National Institute for Astrophysics (INAF) and the University of Bologna. Procurement procedures funded by Italy’s PNRR have concluded, securing the main laboratory equipment and key MORFEO components required for the assembly phase.
Alongside the main hall, a multidisciplinary team is consolidating around the project. The group includes researchers, PhD students, final-year students, research fellows, and technical staff specializing in optics, electronics, complex system integration, and precision metrology. Several Master’s dissertations focusing on MORFEO preparatory activities are finished, while ongoing doctoral projects center on optical alignment procedures, advanced system characterization, and the validation of integration technologies.
Laboratories and Calibration Technology
To support testing, a dedicated optics laboratory now handles functional checks of system components. An advanced simulator laboratory also replicates the operational conditions expected during assembly and verification in Bologna and later in Chile, where optical alignment procedures undergo validation with a precision of a few micrometres.
Complementing physical integration hardware, patented reference calibration methods for adaptive optics systems—such as those detailed in patent records published via scienceon.kisti.re.kr—rely on introducing a controlled light source between the target object and a wavefront modifying device across orthogonal wavefront modes to optimize detector readings and establish precise reference parameter sets.
Future Testing Schedule in Chile
Following the completion of integration and testing at the Bologna Integration Hall, the assembled MORFEO system will ship to the Atacama Desert for installation on the Extremely Large Telescope. The initiative aims to build long-term research infrastructure and technical expertise in Bologna, strengthening Italian participation in major international astronomical instrumentation projects over the coming decades.
Frequently Asked Questions
What is the primary function of MORFEO on the Extremely Large Telescope?
MORFEO acts as an adaptive optics system designed to compensate in real time for atmospheric turbulence, enabling the ELT to utilize the full observational capability of its 39-metre-diameter primary mirror.
Which institutions are leading the development of the integration hall?
The Bologna Integration Hall is a joint centre of excellence established through a synergy between the National Institute for Astrophysics (INAF) and the University of Bologna at the ARIC Research Division.
How are students and researchers involved in the project?
Researchers, PhD students, and university fellows participate in training programs covering precision metrology, optics, and electronics, alongside completed Master’s dissertations and active doctoral projects focused on optical alignment.
Where will the MORFEO system be installed after testing?
Once integration and functional verification are completed at the Bologna facility, the system will be transported and installed on the Extremely Large Telescope currently under construction in Chile’s Atacama Desert.
