小动物激光散斑血流仪

激光散斑血流成像仪采用新兴的LSCI (laser speckle contrast imaging，激光散斑衬比分析成像)技术设计，以独有的非接触、高分辨、全场快速成像的技术优势，为临床医疗及生命科学基础研究提供了一种全新有效的血流监测及血流成像的手段。仪器无需任何造影剂，时间分辨率可达毫秒量级，空间分辨率可达微米量级，实现了科研及医疗人员实时观察微血管的血流分布状态及血流数值相对变化的功能需求。

型号：HR PRO

型号：ZOOM

技术原理简介：

激光散斑（laserspeckle）：当激光照射在相对粗糙(和光的波长相比)的组织表面上,经过不同光程的散射光之间相互干涉，形成随机干涉图样，即散斑。

当被激光照亮的区域经过CCD成像系统时，产生颗粒状或斑纹状像面散斑。如果散射介质（如血细胞）在运动，图象中的每一个象素将产生随时间变化的散斑图样。该图样在时间和空间上的强度变化包含着散射介质的运动信息。通过分析散斑强度在时间和强度变化的空间统计特性，可获得定量的流速信息。

主要特点：

· 全自动变焦，多场景应用
