FROM NEEDS TO SOLUTIONS
100% antenna dimensional inspection for the world’s largest radio telescope: Opto Engineering® vision technologies
Need addressed: automating dimensional quality control for high‑volume antenna production, increasing measurement accuracy and repeatability while reducing manual intervention and inspection time.
In large-scale scientific manufacturing, the ability to perform fast, reliable, and fully repeatable dimensional inspections is essential. This need becomes even more critical when thousands of components must meet absolute quality standards for high-precision applications.
To address this challenge, Sirio Antenne implemented a complete vision-based control system to ensure 100% dimensional verification of antennas for the Square Kilometre Array Observatory (SKAO) project. The solution was developed leveraging Opto Engineering® vision technologies, including software, precision optics, cameras, and illuminators. The integrated solution enables accurate and repeatable measurements, reliable inspection workflows, and high throughput quality control, supporting the production of over 78,000 antennas with consistent and verifiable quality.
INSIDE INNOVATION
What have we been working on during the last months of 2025? At Opto Engineering innovation never stops, from cameras to optics, from software to lighting solutions. This ongoing commitment ensures that our customers always benefit from state-of-the-art solutions that meet the highest standards of precision, reliability, and performance in machine vision.
OEVIS 3.0 now features advanced customization options to better address your specific application needs:
🔵 Custom algorithms
- What’s new: Developers can extend OEVIS® by adding proprietary algorithms to the tool library, leveraging .NET and C++ code.
- Interesting for: Developers with .NET and/or C++ programming skills that need custom vision algorithms or to integrate specific hardware (I/O board, third-party framegrabber, …)
🔵 Custom HMI Control Feature
- What’s new: Build even more customized HMIs using .NET 6.0 WPF (Windows Presentation Foundation framework).
- Interesting for: Advanced users looking for full control over UI design and logic (e.g. add custom data tables, plotting controls, or embed external resources in the machine front-end)
🔵 Custom data types
- What’s new: Users can define their own structured data types for advanced customization. This results in improved data consistency and integration with external systems.
- Interesting for: Advanced users that aggregate different data types to consistently transfer information between multiple threads or that group multiple geometric measurements into a single inspection object for easier handling.
🔵 Enhanced C# Scripting
- What’s new: Developers can now access OEVIS® image processing functionalities directly in C# scripts.
- Interesting for: Users with C# development skills.
