High speed 3-D Surface Profilometry Employing Trapezoidal HSI Phase Shifting Method with Multi-band Calibration for Colour Surface Reconstruction
L C Chen, X L Nguyen, Y S Shu
This article presents a new optical measurement method employing a HSI (Hue, Saturation and Intensity) colour model to form trapezoidal structured patterns for morphology reconstru…
Coherent quantum transport in the presence of a finite-range transversely polarized time-dependent field
C. S. Tang, C. S. Chu
This work investigates the quantum transport in a narrow constriction acted upon by a finite-range transversely polarized time-dependent electric field. A generalized scattering-ma…
Quantum metastability in time-periodic potentials
Chung-Chieh Lee, Choon-Lin Ho
In this paper we investigate quantum metastability of a particle trapped in between an infinite wall and a square barrier, with either a time-periodically oscillating barrier (Mode…
Stabilizing quantum metastable states in a time-periodic potential
Choon-Lin Ho, Chung-Chieh Lee
Metastability of a particle trapped in a well with a time-periodically oscillating barrier is studied in the Floquet formalism. It is shown that the oscillating barrier causes the…
