The close photogrammetric 3-D coordinate measurement is a new measuring technology in the fields of the coordinate measurement machine (CMM) in recent years. In
In order to find the relationships between the distortion rule of the concrete and its surrounding stress field,a real-time optical holographic setup is used to
The surface and interface electronic states of tris-(8-hydroxyquinoline) aluminum (Alq3)/indium-tin oxide (ITO) were measured and analyzed by X-ray photoelectro
The relaxation luminescence of ZnS:Er3+ thin films is studied with luminescence dynamics model. The excitation and emission processes of Er3+ in ZnS host are de
The simulation and analysis of S-shaped waveguide bend are presented.Bend radius larger than 30 mm assures less than 0.5 dB radiation loss for a 4-μm-wide sili
The relationship between gain and carrier density is analysed.In the quantum well(QW) lasers,initially,the gain increases rapidly with the carrier density and t
CdTe films are prepared by closed-space sublimation technology. Dependence of film crystalline on substrate materials and substrate temperature is investigated.
The mechanism of γ-ray radiation induced absorption loss of the optical fiber in visible range is analyzed.According to the mechanism,the quantitative relation
The surface and interface of heterojunction (HJ) formed with organic semiconductor (3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) and inorganic semicondu
An infrared real-time imaging system using DSP(digital signal processor) as the kernel of digital signal processing board is presented. In this system, the imag
