	Self Imaging technique for refocusing an aerospace camera (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Li W.; Li W.; Wang X.; Wang X.; Wang X. 收藏 \| 浏览/下载：33/0 \| 提交时间：2013/03/25 A novel auto-focusing technique using a self imaging approach is developed for an aerospace camera having large aperture and long focus. Its optical system consists of an emitting system receiving system and two penta-prisms. Emitting system has three parts: a light source beamsplitter and aim slit. The receiving system includes a field lens two separate lenses and CCD. Using two little penta-prisms instead of a large planar mirror makes the autofocus system simple and compact. CCD was used as photoelectric converting device. A defocused signal is acquired by measuring the change of the two slit self-images position imaged on the CCD. A simple and compact construction of the auto-focusing system was proposed. The algorithm to calculate the moving of the slit-self images position was analyzed in order to achieve subpixel position estimation. The results of the experiments show a 10m focusing precision. The system demonstrates high resolution easy adjustment and high reliability.
