Paper Abstract
The light absorbed degree of color solution is related to solution concentration, level thickness and incident wavelength.
The blood coagulation analyzer designed with optical heterometry method is lower priced ,and the complete absorbancy
curve can be got ,so it has some advantages for excluded the impact of random errors and further studies. The designed
acquisition circuit are composed of the led, silicon photocell, I/V converter, amplifying circuit, it input the detected
voltage variation signal data to acquisition Card of A/D acquisition terminal then the data is processed by PC. According
to the normalized design ideas, both projective method and scattering method are used in a test. Due to the Acquisition
Card stable performance, high resolution and free from external influence ,so it can collect high-precision data for further
data-processing .In order to improve the test accuracy, collecting data before and after reaction to eliminate ambient light
interference. Verify the feasibility of this design by test APPT, and compare the two methods.
