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

This paper proposed a new approach for the removal of mixed noise. There are many different ways in image denoising. Donoho et al have proposed a method for image de-noising by thresholding
ambiguity is often resulted in determining the correspondence of a modulus maximum to a singularity. In the light
and indeed
we combine the merits of the two techniques to form a new approach for the removal of mixed noise. At first
the application of their method to image denoising has been extremely successful. But the method of Donoho is based on the assumption that the type of noise is only additive Gaussian noise
we used wavelet singularity detection (WSD) technique to analyze singularities of signal and noise. According to the characteristic that wavelet transform modulus maxima of impulse noise rapidly decreases as the scale increases in wavelet domain
which is not successful for impulse noise. Mallat has also presented a method for signal denoising by discriminating the noise and the signal singularities through an analysis of their wavelet transform modulus maxima (WTMM). Nevertheless
it can be accurately located with multiscale space by going through dyadic orthogonal wavelet transform and removed. Furthermore the Gaussian noise is also removed through a level-dependent thresholding algorithm
the tracing of WTMM is not just tedious procedure computationally
algorithm. The experimental results demonstrate that the proposed method can effectively detect impulse noise and remove almost all of the noise while preserve image details very well.
