| Abstract: | With the rapid development of technology,the ballistic camera is also developing in the direction of high resolution and large field of view.Because the existing CCDs can not meet the requirement of large field of view,it is necessary to assemble more CCDs together.In this paper,the technique of optical assembly with area array CCD was studied.Its principle and structure of focal plane were described.The measuring error was anylyzed.The assembly experiment was made on two 1 K×2 K area array CCD for ballistic camera.The experimental results showed that the method had a stitching error of less than 2 μm and a coplanar error of less than 4 μm.It could meet the requirements for measurement of ballistic camera in large field of view and high resolution. |
