中文摘要	in recent years, how to eliminate moving elements while realizing optical zoom imaging has been paid much attention. compared with the conventional optical zooming techniques, removing moving elements would bring in many benefits such as reduction in weight, volume and power cost and so on. the key to implement non-moving-element optical zooming lies in the design of variable curvature mirror (vcm). in order to obtain big enough optical magnification, the vcm should be capable of generating a large variation of saggitus. hence, the mirror material should not be brittle, in other words the corresponding ultimate strength should be high enough to ensure that mirror surface would not be broken during large curvature variation. besides that, the material should have a not too big young's modulus because in this case less force is required to generate a deformation. among all available materials, for instance sic, zerodur and et.al, cfrp (carbon fiber reinforced polymer) satisfies all these requirements and many related research have proven this. in this paper, a cfrp vcm is designed, fabricated and tested. with a diameter of 100mm, a thickness of 2mm and an initial curvature radius of 1740mm, this component could change its curvature radius from 1705mm to 1760mm, which correspond to a saggitus variation of nearly 23μm. the work reported further proves the suitability of cfrp in constructing variable curvature mirror which could generate a large variation of saggitus.
