Considering that the requirement of industrial manufacture
An AT89S51 singlechip works as the core processor of the system. By two laser triangulation
a small thickness measurement system based on PSD and FPGA is presented. It takes S3931 PSD of one dimension as position detection device
A FPGA produces logic control signals for the whole system
the small displacement is converted to differential voltages
which is made by Hamamatsu in Japan
and after amplification and A/D transformation
8-bit parallel data is send to singlechip from FPGA by external interrupts
and the final calculation results output to the LCD display module. After digital micro meter calibration
we get the small thickness. Experiments show that the detection accuracy of the system is not less than 10um.

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.
