我们开发了一台2000 x 8144像素的马赛克CCD相机，它由一个2x8的1000x1018像素的CCD阵列组成。我们使用了从日本德州仪器公司买到的封装的CCD芯片，并在芯片之间的间距略小于芯片尺寸。虽然在两个CCD之间引入了间隙，但这种架构使得建造这种尺寸的摄像头变得容易，甚至为更大的摄像头开辟了一条道路。我们建立了在非平坦的焦面上以所需的精度安装CCD芯片的技术。这架相机现在被用在KISA 105厘米施密特望远镜的主焦点上，用于宽视场测量。
We have developed a 2000 x 8144-pixel mosaic CCD camera, which consists of a 2x8 array of 1000x1018-pixel CCDs. We used packaged CCD chips commercially available from Texas Instruments of Japan and mounted them with a spacing between the CCD chips slightly smaller than the chip size. While gaps were introduced between the CCDs, this architecture made the construction of a camera of this size easy, and even opened a way to larger cameras. We established the technique of mounting CCD chips on a non-flat focal surface with the required accuracy. This camera is now used at the prime focus of the Kisa 105-cm Schmidt telescope for wide-field surveys.
