In the device a He-Ne laser of flash frequency 1-20 Hz was adopted as exciting light source and three key technical problems have been solved successfully in order to enhance the detecting sensitivity and measuring stability of the device for time-resolved fluorimmunoassays(TRFIA) [1]. The first one is to design optimum exciting optical system so that the exciting light beam excite the sample most effectively. The second one is to have a project spectrum filter which can reduce the affection of the background light to the photomultiplier tube and also ensure influence of the stray light and mixed diffusion light to the sample fluorescence to the least the sample fluorescence through the integrating sphere and come to the grating monochromator The right wavelength will be chosed through changing the angle of incidence of the grating monochromator. The third one is to simulate the principle of sample averaging of BOXCAR averager. In the device SCM was used as primary controller and CPLD was used as timing controller. Through the preparation process signal-to-noise ratio(SNR) will be improved also adjust delay time ampling frequency and sampling number arbitrarily. By testing the sensitivity is 10-12mol/L(substance marked by Eu3+) examination repeat is &le2.5% examination linearity is from 10 -8mol/L to 10-12mol/L correlation coefficient is 99.98%(p&le0.01). The instrument is advanced for ultrasensitive detection of antigen and antibody and solve the tumor genetic variation the virus protein detection. 2009 SPIE.

The Raman scattering of I2 liquid-core optical fiber under the condition of resonance absorption in liquid-core optical fiber is studied in this paper. Iodine is dissolved in transparent benzene to make solution of I2 in benzene and the absorption coefficients of the solution are measured at certain wavelengths. The absorption curve can be divided into non-resonance absorption region pre-resonance absorption region strict resonance absorption region and post-resonance absorption region respectively. Resonance absorption Raman scattering experiments are conducted by a 532 nm frequency-doubled Nd:YVO4 laser and the wavelength is in the strict resonance absorption region of solution of I2 in benzene. Compared with I2 the absorption of benzene can be neglected. Non-resonance Raman scattering of the solution is performed using a 632.8 nm He-Ne laser and no spectrum lines of I2 are found. The study demonstrates that there is one spectrum line of I2 in the Raman scattering spectrum in the I 2 liquid-core optical fiber but this line is not found in the spectrum of the non-resonance and resonance absorption Raman scattering of I2 solution in benzene using absorption cell. The experiments proved that I 2 Raman scattering is greatly enhanced by using both resonance absorption and liquid-core optical fiber.
