    • The invention relates to a confocal laser imaging system and method. The system includes a laser source, a beam splitter, focusing elements, and a photosensitive detector. The laser source projects a laser beam along a first optical path at an object to be imaged, and modulates the intensity of the projected laser beam in response to light reflected from the object. A beam splitter directs a portion of the projected laser beam onto a photodetector. The photodetector monitors the intensity of laser output. The laser source can be an electrically scannable array, with a lens or objective assembly for focusing light generated by the array onto the object of interest. As the array is energized, its laser beams scan over the object, and light reflected at each point is returned by the lens to the element of the array from which it originated. A single photosensitive detector element can generate an intensity-representative signal for all lasers of the array. The intensity-representative signal from the photosensitive detector can be processed to provide an image of the object of interest.
    • 本发明涉及共焦激光成像系统和方法。 该系统包括激光源,分束器,聚焦元件和光敏检测器。 激光源沿着要成像的物体沿着第一光路投射激光束,并且响应于从物体反射的光来调制投射的激光束的强度。 分束器将投射的激光束的一部分引导到光电检测器上。 光电探测器监测激光输出的强度。 激光源可以是电可扫描阵列,其具有用于将由阵列产生的光聚焦到感兴趣对象上的透镜或物镜组件。 当阵列通电时,其激光束在物体上扫描,并且在每个点处反射的光被透镜返回到从其发射的阵列的元件。 单个光敏检测器元件可以为阵列的所有激光器产生强度代表性信号。 可以处理来自光敏检测器的强度代表信号以提供感兴趣对象的图像。
