Automatic compensation of thermal drift of laser beam through thermal balancing based on different linear expansions of metals
We present a technique for compensating laser beam up-shifting induced by the hot air with temperature-gradient in a 2D-scaning laser radar for monitoring the intruder in the railway system, in which the laser beam is scanning at a height only a few centimeters above the railway tracks so that any o...
