Bc. Li et al., PULSED PHOTOTHERMAL INTERFEROMETRIC DETECTION FOR THERMAL-DIFFUSIVITYMEASUREMENTS OF TRANSPARENT PLATE SAMPLES, Progress in Natural Science, 6, 1996, pp. 657-660
A simple, sensitive pulsed photothermal interferometric detection tech
nique utilizing the interference of two reflected probe beams from the
front and rear surfaces of a plate sample to detect the photothermal
signal was developed. This technique was used to measure the thermal d
iffusivity of plate fluoroaluminate glass doped with Erbium ions.
