Surface roughness measurement using dichromatic speckle pattern: an experimental study.

Surface roughness is studied experimentally by making use of the statistical properties of dichromatic speckle patterns. The rms intensity difference between two speckle patterns produced by two argon laser lines are analyzed in the far field as functions of the object surface roughness and the difference in the two wavenumbers of the illuminating light. By applying previously derived formulas,...

Development of 3D measurement system using phase-shift digital holography

We propose a digital holography reconstruction method using convolution approach rather than the conventional Fresnel approach. Simultaneously, we propose a 3D measurement system of phase-shift digital holography using principle of light detector. Using proposal method, we develop a compact 3D measurement system of phase-shift digital holography with low price and high measurement accuracy. Key...

Absolute measurement of surface roughness.

In an interferometer which uses a reference surface, the measured surface heights correspond to the difference between the test and reference surfaces. To accurately determine the rms roughness of supersmooth surfaces, the effects of the reference surface roughness need to be removed. One technique for doing this involves averaging a number of uncorrelated measurements of a mirror to generate a...

Tomographic three-dimensional imaging of a biological specimen using wavelength-scanning digital interference holography.

The principle of wavelength-scanning digital interference holography is applied to three-dimensional imaging of a small biological specimen. The images are reconstructed from a number of holograms digitally recorded while the wavelengths are varied at regular intervals, and the numerical interference of the multiple three-dimensional hologram fields results in tomographic images with narrow axi...
