摘要:
An optical unit includes a plate having a fixed position, an optical element having a specific optical action, a fixing device for partially fixing the optical element, and a deforming device, located between the plate and the optical element, for applying a deforming force to the optical element to asymmetrically change a surface shape of the optical element.
