โœฆ Synopsis

Talbot interferometry with a larger applicable scope has been investigated based on the intensity ampliรฟcation method to weak moirรƒ e fringes by using photorefractive crystal as a light ampliรฟer. It not only has function of conventional Talbot interferometry, but also is suitable for situations such as weak incident beam and detected object with strong absorption. The investigation indicates that the method or technique is feasible and the results of theoretical analysis are veriรฟed by experiments. Based on this investigation, Talbot interferometry with an adaptive light intensity compensator is proposed and some merits and demerits of the technique have brie y been discussed.

Electron motion between resonant states in an intensive light field results in variation of equilibrium positions of nuclei with time, and this causes variation of the energy of the excited electron state. This is the reason why oscillations in the populations of electronic states and equilibrium po

## Abstract This study evaluated the effect of high light intensity using a plasma arc lamp on the cavity wall adaptation of photoโ€polymerized composite restorations. Bowlโ€shaped cavities were prepared on the labial surfaces of extracted bovine teeth. Each cavity was restored with a resin composite
