| 摘 要： | IntroductionIf let roadway entities be denoted by arcs and in-tersections be denoted by nodes, then a road net-work can be represented with node-arc model. Be-cause the designation of nodes can be determinedby arcs according to the definition of node-arc …

| Abstract: | ring,Xi'an Jiaotong University,Xi'an 710049,CHN;2.Department of Electronic Engineering,Engineering University of Air Force,Xi'an 710038,CHN)A method to measure scattering media's interface roughness with optical coherence microscopy(OCM) is proposed,which is based on low coherence interferometry and confocal microscopy.The axial resolution of OCM system is determined by confocal gate and coherence gate.However,OCM is more effective in the rejection of out of focus and multiple scattered photons originating further away of the focal plane.With the three-dimensional scanning,the interfd approaches to representing other roadways with carriageways are introduced. At last, an overall architecture of the CRNM is proposed. |
