Article tables are available to subscribers only. The uncertainty relating to the construction of the device, geometrical features, operating environment and optical characteristics is also presented. Phys.

Radial, axial and tilt motions are also simulated by making comparisons with the given displacements and the simulation values respectively. Print. Orthogonal reference signals are generated using direct digital frequency synthesizer (DDS) and mixed with the output of a photo-detector. Phys.

The electrical time-domain signal was analyzed in the Fourier-domain in order to detect a hole-like reflector in an austenitic stainless steel specimen. Simulation results indicated that the transmission was as low as 0.03 at ~0.79 THz. Makobore; C. We have obtained surface relief modulation in single step processing on the photo resist and polysiloxane films.

Article level metrics are available to subscribers only. more info here A precise angle dividing table (PADT) was chosen as the reference to verify the angle measurement error of this method. The experimental results showed a significant geometrical imaging of the reflector shape with the scanned data. Usage and citation metrics Please see the page article level metrics in IOPscience for more information about the statistics available.

As a result, the noise in the loop circuit was suppressed; this resolved the current instability problem in eddy current sensor. useful reference Four iGPS transmitters were set around the test site. Abstract. ... 5, 879 (2005). It operates independently of a user's location or IP address.

The results demonstrate the usefulness of the technique for a non-invasive and rapid inspection of submicron-scale domains otherwise not visible by the conventional non-destructive methods available nowadays.BookmarkbyPietro Ferraro7Condensed Matter Physics,Ferroelectrics,Etching,Diffraction GratingsImproving The problem that dielectric loaded inducing the transmission loss in the centre of the frequency response curve is difficult to be avoided. We present the method to decompose the images by nonsubsampled contourlet transform and wavelet successively, and fuse the images in the compressive domain.

Unfortunately, as the other side of the coin, the introduction of SDR concept and band sampling method induce negative influence on the performance of the GNSS receivers. In the subsystem, the initial phase of the interference signal, which was caused by the initial optical path difference between interference arms, could be demodulated using phase generated carrier (PGC) method Matter (1989 - present) J. A reflective cylindrical holographic diffraction grating fabricated into cylindrical shape, referred to as the `length master', acts as the moving part governing the path length of light.

The measuring results showed that the compensation method satisfied with the need of measuring accuracy. Similar result of FFE is obtained as 0.891 μm for the aspheric lens by the developed method than FFE 0.896 μm by the UA3P software. Opt. (1995 - 1998) Rep. Semicond. (2009 - present) J.
