With the advance of contemporary technology, high precision surface finishing techniques for optical glasses are of great concern and developing to meet the requirements of the effective industrialized processes.
Large-scale compact range generally consists of multi reflectors, how to align these numerous small reflectors into a high precision surface, this has to be carefully taken into account following two key issues: measurement system and alignment approach.
In this paper, a new recovery algorithm is presented, in which correlation analysis of WLI envelop curves and a multi reference position based phase solution method are employed for robust and high precision surface recovery.
The random path is claimed to be useful for reducing the MSF error, [12] but is hard to achieve a high precision surface form because of the difficulty in tool speed management [7].
Examples include electron ptychography [6], 3D atomic reconstructions using dynamical scattering [7], high precision surface atom position measurements on catalytic particles [8], de-noising routines [9], phase contrast imaging with phase plates [10], new dynamical atomic contrast models [11], atomic electron tomography (AET) [12 16], and many others.
Suppliers of metallic components with high-precision surfaces are facing a trend towards zero-defect tolerance regarding their finishing.
We describe an industrial interferometer designed to conduct high-precision surface measurements in the presence of severe vibration.
Since the atomic force microscope (AFM) was invented in 1986, it has been commonly utilized as a high-precision surface profiler [6].
However, a recent study using a high-precision, surface-based diffeomorphic technique in neuroleptic-naïve adults with Tourette syndrome failed to show any significant volume or shape differences in the basal ganglia or thalamus (Wang et al., 2007).
Development of instrumentation for high precision local surface wave velocity measurement will be presented.
