The mobilities of holes in thin,spin-casting films of poly(N-vinylcarbazole)(PVK) based on silicium are measured using a time-of-flight(TOF)technique.The drift
A technique of fast 360°spinning 3D measurement is realized.A laser diode used as light source produces 0.5mm wide slit which is projected onto the surface
The principle of a new optical fiber temperature transducer is presented,and ingenious design scheme of this transducer is given.Because taking the special modu
Work has been done with extending the useful imaging and detection rage of CCD.This was accomplished through direct optical coupling and bonding of image intens
The investigation on optical properties of Si1-xGex/Si strained layer structures has been carried out actively in recent years.The photoluminescence has be-come
The Dirac symbol is used to represent the discrete complex Hopfield neural network model.The signal-to-noise theory and the computer numerical solu-tion are mad
When recording a hologram,we should control the.exposure amount which is in nonlinear area of the characteristic curve of complex amplitude transmittance τ~expo
