Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk Institute of Science and Technology (DGIST), has successfully developed an ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Melbourne, Australia: It's not the size of the interferometer that matters; it's how you use it. So claim a team of researchers from RMIT University, the University of Sydney and University of ...
