公司介绍:
成立于2008年的greateyes,是以德国柏林洪堡大学的技术为基础,迅速发展成为国际知名的先进探测器生产企业。如今,其科研与工业客户群体已遍布多个国家。
greateyes开发、生产并销售高性能科学相机。其作为精确探测器,被广泛应用于成像与谱学应用领域。同时,greateyes公司也生产用于太阳能产业的电致荧光与光致荧光检测系统。
产品介绍:
来自greateyes的科学级超高分辨CCD为红外到X射线区域光谱分析及成像应用的客户提供了一种全新的选择。其核心来源于用最新的技术为用户提供了亚像素分辨的能力,与标准的科学级CCD相比,科学级超高分辨CCD以其超低的读出噪声、极高的量子化效率、极低的暗电流以及超高的动态范围提供了更好的空间及光谱分辨能力,实现过程是通过亚像素微米范围内探测器的移动,同时抓取不同图像生成具有较高分辨的图像。整个图像采集过程实现了全自动化。独一无二的超高分辨技术可应用于所有greateyes科学级CCD系列,详细参数请参照相应系列的CCD参数。
技术原理:
科学级超高分辨CCD在图像传感器和制冷元件后方集成了一个非常紧凑的X-Y位移装置。通过软件用户可选择预定义的测量顺序以达到期望的空间分辨率。例如,2 x 2的图像子集下,最终图像尺寸增至相机图像传感器的4倍。软件采集2 x 2 = 4帧顺序图,每帧下传感器在x与y方向上移动亚像素微米级的距离。并通过算法将各帧图像合成最终的超分辨图像。
超高分辨图像的获取与单个图像的获取一样简单。所有其他性能参数与greateyes科学级CCD相同。
