FPGA Based Linear Heating System for Measurement of Thermoluminescence

Abstract

A linear heating system has been developed using field programmable gate array (FPGA) for the measurement of thermoluminescence (TL) in alkali halides and other related compounds. Thermoluminescence plays an essential part in radiation dosimetry. This system measures the temperature and the amount of light emitted by the sample for TL studies. This work proposed an architectural framework, verilog HDL code for protocols for reading temperature from Thermocouple through ADC, processing of data (amount of light energy) in FPGA, sending control signal to the heater and displaying the temperature in LCD. This work shows performance improvement 3 times in comparison with conventional embedded system. The power consumption is also comparatively lower.

An Efficiency Multiplexing Scheme and Improved Sampling Method for Multichannel Data Acquisition System

“…They usually employ different structures in terms of different applications and have some vastly variations, which can be seen in the performance and cost [1][2][3]. In some applications, a large number of parameters need to be measured, and these desired signals always have different frequency bandwidths with the range from Hz to kHz.…”

“…Nowadays, data acquisition systems are widely used in aerospace system testing, industrial automation, medical diagnosis, communications, and other various industries. They usually employ different structures in terms of different applications and have some vastly variations, which can be seen in the performance and cost [1][2][3]. In some applications, a large number of parameters need to be measured, and these desired signals always have different frequency bandwidths with the range from Hz to kHz.…”
