Also a specialized Testing Division for a variety of environmental tests to serve other companies and institutions.
Q. What are Electro-optical imaging systems? How LIDAX electro-optical systems different from other imaging systems available in the market?
Stefano Li Bassi: LIDAX Electro-Optical Systems is a startup within the LIDAX group. It focuses on addressing the needs of a sector or a group of clients when they cannot find a suitable product or solution in the market. If the business case proves to be promising, LIDAX EOS takes the lead in forming a consortium, identifying the necessary technology providers (R&D centers or universities) to develop a fully functional system, and ultimately commercializing an innovative and unique product.
Currently, the company is developing SISTAM, a system leveraging DeepTech technology for in-depth structural assessment of bridges and viaducts, tailored for global companies operating in the civil infrastructure maintenance and conservation market.
Q. What is opto-thermomechanical and cryogenic systems? What are its unique advantages in space-based instruments and their impact on satellite missions?
Stefano Li Bassi: LIDAX develops cryogenic systems designed to operate reliably in both cryogenic and ambient conditions, while withstanding the harsh environment of space. A prime example is LIDAX's contribution to the James Webb Space Telescope: the MIRI simulator. This crucial component enables the performance of critical simulation tests at an extremely low temperature of 25 Kelvin.
Furthermore, LIDAX has pioneered the development of a cryogenic heat switch. This innovative technology allows for precise and secure control of cryogenic systems. It operates by automatically switching between cryogenic fingers, eliminating energy dissipation due to its passive nature.
Q. What are the ISO 5 and ISO 7 cleanrooms facilities for optical and opto-mechanical integration procedures?
Stefano Li Bassi: Space optical units, require a carefully controlled integration environment to avoid the smallest pollution to interfere with image detection process, that’s why LIDAX makes available ISO 5 and ISO 7 particle count clean rooms, along with highly experienced personnel to carry out different processes, from integration to testing of optic devices, intended for space operation.
Q. What is SISTAM, the advanced inspection system designed for evaluating civil infrastructures?
Stefano Li Bassi: SISTAM is a non-invasive and non-destructive system designed for inspecting civil infrastructure, such as bridges and viaducts, detecting chemical issues that traditional techniques cannot identify. It is currently under development by LIDAX Electro-Optical Systems and will be capable of penetrating deep into structures to detect and quantify internal degradation. This disruptive and innovative solution will enable rapid and cost-effective detection of potential failures in civil infrastructure, significantly reducing inspection times.
Q. What is the role of space simulation and testing facilities in ensuring the success of the products?
Stefano Li Bassi: Space missions demand exceptional reliability. Once an instrument is in orbit, the possibility for on-site repairs is virtually nonexistent. To mitigate the risk of critical failures, rigorous testing is paramount. Every component, mechanism, and system must undergo rigorous testing in environments that accurately simulate the harsh conditions of space.
LIDAX offers its expertise to other companies and institutions, providing the facilities and personnel necessary to design and conduct these crucial tests. By ensuring that space-bound technologies withstand the extreme temperatures, vibrations, and radiation of the space environment, LIDAX contributes to the success of critical space missions.
Q. How does the state-of-the-art manufacturing processes ensure the highest standards in optical and thermal systems?
Stefano Li Bassi: State-of-the-art manufacturing processes for optical and thermal systems prioritize the highest standards through a combination of advanced techniques. Thermal control is achieved through a multifaceted approach, employing cryogenic techniques, high-emissivity coatings, and active cooling mechanisms. Rigorous environmental testing, encompassing vibration, thermal vacuum, and contamination control, ensures the reliability of these systems in the harsh conditions of space.
Nanometer-level metrology and automated alignment guarantee sub-micron accuracy, essential for optimal performance. This meticulous approach, incorporating advanced thermal control and rigorous testing, ensures these systems excel in the extreme space environment.
Q. What are the design considerations for developing thermal straps in maintaining thermal equilibrium in spacecraft?
Stefano Li Bassi: Developing effective thermal straps for spacecraft requires careful consideration. These components must efficiently transfer heat while maintaining flexibility to accommodate mechanical stresses.
LIDAX possesses the expertise to select the most suitable materials, such as copper and pyrolytic graphite, based on a thorough trade-off analysis considering thermal requirements, mass constraints, and specific application demands. Seamless integration with other thermal control elements, such as radiators and heat pipes, is crucial for effective thermal control system design.
Furthermore, these straps must withstand extreme temperatures, radiation, and launch conditions without degradation, while minimizing outgassing to prevent contamination. Rigorous testing, encompassing simulations of microgravity, launch vibrations, and prolonged space exposure, is essential to ensure their durability and reliability in maintaining thermal equilibrium across the spacecraft.
Q. How does LIDAX’s opto-mechanical, thermal and cryogenic systems address the challenges in space and what makes it stand out compared to other solutions in the market?
