For example, convert a point spot into a line spot, or change the height of the image without changing the width of the image. It can be used in linear detector lighting, barcode scanning, holographic lighting, optical information processing, computers, and laser emission. Optical cylindrical mirrors are also widely used in high-power laser systems and synchrotron radiation beam lines.
