Laser Flash Method

This program is designed to measure thermophysical properties of materials (thermal diffusivity and specific heat) by the laser flash method. A huge thanks to ULVAC RICO Inc.(Japan), whose equipment is still in operation and for which this program is implemented. The measurements are performed by a multifunctional analog input board PCI-1710UL (ADVANTECH, Taiwan), which is used as a variable-frequency signal recorder (in range 40 Hz – 40 KHz). The program is designed for simultaneous use of two TC3000 units. The measurement is triggered when an external trigger signal from a ruby laser is applied to one of the digit of digital I/O port of the PCI-1710UL board. The program includes a help system called F1. The application uses an external library (Advantech DAQNavi SDK) and driver to control the PCI-1710UL board.
