Aerosol Optical Depth (AOD) is of great value for studying air mass and its changes. In this paper, we studied the spatial-temporal changes of AOD and its driving factors based on spatial autocorrelat...
MEASURING THE GROWTH OF INDIVIDUAL TREES USING MULTI-TEMPORAL AIRBORNE LASER SCANNING POINT CLOUDS
Height growth laser scanning multi-temporal change detection
font style='font-size:12px;'>
2015/8/13
It is well known that characteristics of individual trees, such as tree height, biomass and crown area, can be derived from airborne
laser scanning (ALS) and that heights for individual trees can be ...

Abstract: Recent research has uncovered a remarkable ability to manipulate and control electromagnetic fields to produce effects such as perfect imaging and spatial cloaking. To achieve spatial cloaki...
Spectral and temporal characterization of a fused-quartz microresonator optical frequency comb
Spectral and temporal characterization fused-quartz microresonator optical frequency comb
font style='font-size:12px;'>
2011/9/1
We report on the fabrication of high-Q, fused-quartz microresonators and the parametric genera-tion of a frequency comb with 36 GHz line spacing using them. We have characterized the intrinsic stabili...
Temporal coherence length of light in semiclassical field theory models
Temporal coherence length light semiclassical field theory models

2010/10/29
The following work is motivated by the conceptual problems associated with the wave-particle duality and the notion of the photon. Two simple classical models for radiation from individual emitters ar...
Laser Beams with Spatio-Temporal Phase Modulation
Coherence control Partially coherent light Speckle smoothing
font style='font-size:12px;'>
2009/6/8
This paper reviews a method of the irradiance profile smoothing on the high-power laser system. In the multi-beam laser irradiation geometry, the coherence control of laser beam is necessary to reduce...
