Centre for Sensors, Instruments and Systems Development
CD6’s activity focuses on developing research and technological applications in the field of Optical Metrology and Photonics. The centre's researchers (whose specialist fields include optical engineering, mechanics, electronics and software) have four main lines of research:
Non-contact measurements of surface topography and roughness, time-of-flight imaging, self-mixing interferometry, 3D body scanning, fringe projection, Confocal profilometry, deflectometry.
Optical design and simulation
Design of optical systems and sensors, LED lighting, optical instruments, ophthalmic lenses, intraocular lenses, active optics, adaptive optics, development of new instrumentation.
Biophysics, biophotonics, optical instrumentation, physiological optics, ophthalmic optics, visual optics, Shack–Hartmann wavefront sensors.
Imaging sensors, hyperspectral systems, multispectral systems, spectral technology.
CD6’s activity has resulted in many scientific contributions being published in international journals, 32 patents (several of which are being exploited) and the creation of 5 new spin-offs exploiting the centre’s research results.
Currently 4 patents are available to out-license:
- A method of measuring a displacement-related parameter using a laser self- mixing measuring system, and a laser self-mixing measuring system (EP10380130.4)
- Method and system to compensate optical aberrations in a telescope (P201001030)
- System and procedure to measure roughness of a paper sample by Speckle texture analysis (P201130708)
- System for receiving a light beam (EP11002231)
Optical engineering is a technology that can be applied to many fields, enabling CD6 to acquire many clients in a wide range of sectors, including:
New, non-invasive applications can be developed to create new diagnosis tools, therapies and surgical techniques in high-resolution 3D imaging, ophthalmology and new technical instrumentation.
Optical sensors can be used to acquire information in real time, enable vision beyond the visible spectrum or enable the use of high-resolution cameras in industry. Other examples of optical sensors are found in Earth-observation systems and equipment for detecting pollutants.
Lighting, displays and screens (overhead panels on motorways, mobile phones, etc.) that combine functionality with low energy consumption. CD6 has also worked on the characterisation of light sources, the design of lighting systems (vehicle interiors, street lighting, etc.) and signalling systems (traffic lights, motorway panels, etc.).
Optical devices to ensure the quality of manufactured products or to reduce costs during the manufacturing process. Optical technologies such as lasers have opened the door to improving cutting and welding processes and the manufacture of micrometer-scale mechanical components.
CD6 has developed optical devices for vehicles of all kinds, pollution and pollutant sensors, food quality control systems, biometrics systems and border-control equipment.
Creation of the first adaptive optics (AO) measurement system, through the combination of three innovations. This system allows real-time compensation of the distortion induced by the atmosphere in large astronomical telescopes (using active optical elements), enabling a significant reduction of the atmosphere in large astronomical telescopes (using active optical elements), leading to a significant reduction (by almost two thirds) in the cost of the mechanics of the telescope and an improvement in image quality to professional levels. This project resulted in a patent.
The goal is to develop new advanced instrumentation techniques based on optoelectronic imaging sensors to be used for improving vision: the measurement of ocular aberrations (improving existing systems) and a new system to objectively measure intraocular scattered light (currently no system exists to measure this). In the field of colour technology, CD6 is developing advanced instrumentation to measure colour using image sensors.
The development of new industrial processes to design, manufacture and control the qualitative measurement sensors for accumulated pollution levels in outdoor environments. These processes are based on qualitative optical measurements. To validate the technology, CD6 has developed specific applications such as measuring accumulated pollution on monuments and historic buildings, in road tunnels, etc.
The project envisages developing a method to measure the roughness of paper by analysing the speckle pattern on the surface. Surface roughness is an important parameter for paper and card used for printing, since it affects the amount of coating needed and the application method used.
