Abstract:By measuring the magneto capacitance spectroscopy of an n type InSb metal insulator semiconductor (MIS) structure, the 2 dimensional hole subband in the p type channel of the InSb MIS device was investigated under different magnetic fields at 1 2K.It was shown that the on set energy of the p type channel has a strong dependence on the magnetic field. This behavior has been attributed mainly to the dependence of the InSb band gap energy on magnetic field.

Abstract:The vibrational modes in Hg 1- x Cd x Te epitaxial films were investigated by means of far infrared transmission spectra at temperatures from 4 2 to 300K.The observations were put forward in the spectral range from 20cm -1 to 350cm -1 , emphasizing the wavenumber region at the low frequency side of the reststrahlen absorption band.A series of single phonon and two phonon modes, defects induced vibrational modes and impurities levels were observed.

Abstract:The synthetical application of the oscillator model and Kramers Kronig relation to the far infrared reflection spectrum of the long wavelength optical phonon in crystals was reported. By using the restriction condition between the oscillator model and the Kramers Kronig relation, a method was proposed to reckon the dielectric function from the incomplete far infrared reflection spectrum.

Abstract:A method using neural network to recognize targets according to the output of the multichannel optical correlator was proposed. The position of the correlation peaks was found through statistical rules. Not only the self correlation peaks but also the cross correlation peaks were used to be the features of the targets and the complex feature extraction was realized through neural network. The proposed method can effectively exclude the effects of the target background interference and the fluctuation of the device performance so as to realize a real time target recognition.

Abstract:A method named MACA (Modified Active Contour Algorithm) was suggested.In the general Snake model, there is no required matching between orientation of the contour and edge direction in the gray level image.This kind of Snake model may fail in the images with rich texture or with concave objects.To avoid it, two energy functions based on the above mentioned ideas were proposed to improve the Snake model.To reduce the time cost in the iteration of MACA, a FGA(Fast Greedy Algorithm) was proposed. Also, the first order derivative and the second order, domain of searching area, contour resampling, and conditions of corner locking were redefined. Experimental results show that the proposed method is much better than the general Snake model,especially on searching for concave objects.
