Magnetostriction quasi-static measurements with laser Doppler effect
A quasi-static method for measuring the magnetostrictive coefficient of Fe-Ga alloys by using laser Doppler effect was put forward, and its working principle was also analyzed. The quasi-static magnetostrictive coefficient of Galfenol was measured.

Christian Doppler and the Doppler effect
A summary is given of Doppler's life and career. He was born 180 years ago on November 29, 1803, in Salzburg, Austria. He died on March 17, 1853 in Venice. The effect bearing his name was first announced in a presentation before the Royal Bohemian Society of the Sciences in Prague on May 25, 1842.
