Moiré Topography: From Takasaki Till Present Day

Topography of the graphene/Ir(111) moiré studied by surface x-ray diffraction

Moiré topography.

Contour moiré pictures with good contrast of a full size living body are now available. Construction problems, performance, and accuracy of large instruments are experimentally studied. Techniques to minimize the drawbacks of the moiré contouring are developed. The system has been proved to be ready for practical application to full size living bodies.

Pattern Recognition using Moiré Fringe Topography and Rasterstereography

Moiré fringe topography and rasterstereography are 3-D optical imaging techniques, which provide height and curvature maps of the subject or the object under study. These are non-contact and non-invasive techniques, which project moiré and raster grids on the body. The distorted grids contain height and curvature information, which may be recovered using image-processing algorithms. These techn...

Phase-shifting Deflectometric Moiré Topography

This paper presents a moiré-based technique for measuring the threedimensional shapes of specular surfaces. In it, a Ronchi grating is closely located before the measured object and illuminated by diffusive light sources. When we observe the measured object through this grating, moiré fringes are generated by the superposition of this grating and its virtual image produced by the measured specu...

3-D micro-structure measurement method based on shadow moiré using Scanning

The novel precise three dimensional shape measurement method using SEM and moiré topography has been proposed. The possibility for measurement of wave length order by this method has been discussed using the results of experiments for confirming the principle of this idea. In the experiments, the method with high resolution power based on the new measurement method is also proposed by employing...
