When breaking imaging rules leads to out-of-focus, we need the machine vision system to adjust its optical parameters quickly and intelligently. So we can get clear and usable images. On the other aspect, out-of-focus only depends on the optical parameters which contain the depth information of objects. By using the information, we can recover the three-dimensional image of the objects.

Based on the relationship between the numerical aperture of the objective lens and scale pitch, this study chooses a suitable Plano-convex lenses available on the market, so as to approximate the diameter of the focusing spots to scale pitch. Also, by using the optical path of an optical encoder similar to the nanoscale, the changes in the surface profile of the scale can be measured directly, so as to obtain the two quadrature sinusoidal signals. By counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the scale can be obtained.
