    • A new high resolution confocal and non-confocal scanning laser macroscope is disclosed which achieves fine focus and control of focus position by moving a lens in the intermediate optics. This arrangement is particularly useful for imaging specimens where it is difficult to focus by changing the distance between the scan lens and the specimen, for example for in-vivo imaging, photodynamic therapy, and image-guided surgery. It is also important to keep the lens-to-specimen distance constant when a liquid-immersion scan lens is used, in order to maintain a constant thickness of liquid between the lens and the specimen. In addition to being useful for confocal slicing, motion of the intermediate lens under computer control also enables dynamic focus and the ability to move the focal spot along a general path inside the specimen. Several applications of the imaging system are described. The macroscope images macroscopic specimens in reflected light, transmitted light, fluorescence, photoluminescence and multi-photon fluorescence.
    • 公开了一种新的高分辨率共焦和非共焦扫描激光宏观显示器,其通过在中间光学器件中移动透镜来实现聚焦位置的精细对焦和控制。 这种布置对于通过改变扫描透镜和样本之间的距离难以聚焦的成像样品特别有用,例如用于体内成像,光动力学治疗和图像引导手术。 当使用液浸式扫描透镜时,保持透镜与样本之间的距离恒定也是重要的,以便在透镜和样本之间保持恒定的液体厚度。 除了用于共聚焦切片之外,中间透镜在计算机控制下的运动还能够实现动态聚焦和沿着标本内的通用路径移动焦点的能力。 描述成像系统的几个应用。 宏观图像宏观样本在反射光,透射光,荧光,光致发光和多光子荧光。
