1.In AOD laser beam scanning manufacturing system,there was non-linearity mapping relation between the output Cartesian coordinates of object lens scanning plane system and the coordinate of AOD driver.
2.In the dual-galvanometric laser scanning,there was non-linearity mapping relation between the output Cartesian coordinates of object lens scanning plane system and the coordinate of laser scanner. It made the laser scanning geometry to be distorted.
3.An optically formed duplicate, counterpart, or other representative reproduction of an object, especially an optical reproduction of an object formed by a lens or mirror.
4.A mirror, lens, or combination of lenses used to gather light and direct it upon an object or through a projection lens.
6.The lens or lens system in a microscope or other optical instrument that first receives light rays from the object and forms the image.
7.By using knife edge as object,and CMOS sensor as device for image analyzing,we get edge spread function from the image and use differential operation and FFT to obtain modulation transfer function of the lens,then its image quality is known.
8.The system is on the basis of Fourier Optics. By using knife edge as object, CMOS sensor as device for image reception, we get edge spread function from the image histogram and use differential operation and FFT to achieve MTF of the lens, then its image quality is obtained.
