TNO's Optomechatronics department knows how to design, realize and test mechatronical systems for optical applications requiring extreme stability, highly accurate and fast motion, and / or operation in extreme environments. The most important fields of expertise that TNO covers are precision mechanics, mechatronics and control. Optomechatronics have built systems for space, astronomy, semicon and for nuclear fusion projects.
TNO translates customer's wishes into technical requirements. This in combination with knowledge of the market and technical risks yields valuable projects. TNO's inter-disciplinary approach to come to system architecture, design, manufacturing and testing has a large added value. The most important disciplines that are covered are precision mechanics, mechatronics and control. Precision mechanics focuses on achieving extreme structural stability, specific stiffness and predictable motion behavior. TNO has knowledge on the mounting of optics, precision design principles and the prediction of the system's stability. Precision mechatronics focuses on realization of very stable positioning and / or accurate motion. TNO combines dynamic system modeling and design approach with knowledge of and experience with metrology principles and of sensors and actuators. Control allows for further increasing the performance. TNO focuses, amongst PID- and MIMO control and its implementation, on optimal-, nonlinear - and adaptive control.
TNO knows how to design, manufacture, test and deliver systems that meet extreme requirements. Examples are:
TNO recently realized a large scale mechatronic system that performs better on earth than the final instrument will do in space. AFMA is designed and built for ESA. It simulates GAIA's rotations in space in three degrees of freedom. The accuracy of the important scanning direction is very high: 3.2 nrad per 4,4 s
OTA consists of an a-thermalized stable 20x optical beam expander with an in-house manufactured a-spherical lens of Ø380 mm and an extremely stable mirror pointing mechanism with custom actuators. The first OTA is recently tested resulting in a very satisfied customer.
TNO has, with MECAL, developed a solution to suppress disturbing vibrations in high-tech machinery with a factor 30. Also at low frequencies, while the robustness for e.g. motions of the machine is maintained. A key component is the custom designed sensor that yields very low noise.
