Beijing's roads are built in the Ming Dynasty, because the Ming Dynasty骑射poor people, in order to prevent军攻Mongolia has run into the city after, obviously narrow urban road, and alley entrance dislocation for infantry street fighting, so that Beijing's roads are in accordance with the Sedan Chair son of street fighting infantry designed from the Sedan Chair son walk to the car traffic, the "generation gap" can be imagined.

北京市的道路是明代修建的，因为明朝人不善骑射，为了防止蒙古军攻入城后长驱直入，城市道路明显偏窄，且胡同口错位，便于步兵巷战，因此，北京的道路是按照抬轿子、步兵巷战设计的，从抬轿子、步行到汽车交通，这个&代沟&可想而知。

In order to obtain the correct height reconstruction of a measured object through the traditional Fourier transform profilometry, the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens must be horizontal and set to parallel to the reference plane.
