In this study, we propose a new micro-optical system with 1.65 zoom ratio for image stitching. The new system with four layers is based on microlens and liquid lens arrays. In order to realize the zoom function, we design the first and the fourth layers by the liquid lens and we also set up the second and the third layers as the fixed lens to tilt the optical axes. The length of the system is 6.4 mm, the image size 8.6 x 6.6 mm2, the field of view(FOV) 50° in wide mode and the field of view 28° in tele mode. The MTF and distortion are used to demonstrate the zoom function, the stitching function and the stitching with zoom function, respectively. In the results, we use the ZEMAX ray-tracing software to demonstrate the simulation of image stitching in wide and tele modes.
