an χ-γ dosimeter has been developed in our laboratory.The new method of voltage-to-frequency conversion is adopted in the design
and this enables long-distance transmission of analog signals in the form of frequency
with improved ability of interference resistance and dosimetry accuracy.Combining FPGA with SOPC technology
with embed equal precision measurement module and MC8051 IP core
data acquisition
computation and display of the χ-γ dosimeter are realized
with improved performance in terms of measurement speed
precision and system flexibility.Principles of the circuit modules and design methodology are given in detail in this paper.Test results proved that the design is of advantages.
