Late Pennsylvanian cyclothems are documented from the carbonate platform margin in Guizhou, South China, providing a unique opportunity to study glacio-eustatic fluctuations and their impact on reef development. This paper focuses on a shallow-water,

Stromatolites, among the earliest fossils in Earth’s history, are widely distributed on the margins of the North China Precambrian carbonate platform. The formation processes of stromatolites reveal the biomineralization and evolution of early life

In this paper, we propose a simple, compact surface profilometer based on a fiber-coupled self-mixing interference (SMI) system and the confocal scanning principle, in which the surface microprofile is determined. Analysis of the confocal property in

A novel self-mixing interferometer with a double external cavity was proposed to measure absolute distance and microscopic displacement. The technique developed uses an additional reference reflector to form an external dual cavity between the laser

Smart optical sensors for the displacement measurement in submicron, have been developed by using the self-mixing effect of a laser diode. In this article, we propose a new type of self-mixing interferometry (SMI) to measure microscopic displacement.

We report a method for determining the spring constant of an optical trap by external sinusoidal excitation and lock-in detection. A polystyrene latex particle trapped in a focused Nd:YAG laser beam is forced to oscillate by another intensity-modulat
