To simulate the variable process of target imaging,an IR zoom system with ratio of 17x is designed. To en-sure the stability of image position in zoom system,the zoom fitting curve is calculated by applying dynamic optics and building mathematical model in Matlab. Focusing on zoom system structure, the detail structure is designed and ana-lyzed. According to physical restriction conditions,the relationships among cam diameter,work rotating angle and screw lead angle is analyzed. Experiments show image position is stable,zoom system gets better image quality based on the curve from dynamic optics design in zoom.
