Fig. 5From: Transient dynamical-thermal-optical system modeling and simulationThe temperature distribution on the lens after three seconds (left) and the images for t=0s,t=2s and t=3s. The higher the changes in the refraction index due to temperature is, the more orange are the ray positions on the image plane. The red dot shows the center of the cylinder within which the heat is applied on the lensBack to article page
