Full-color, three-dimensional images of objects under incoherent illumination are obtained by a digital holography technique. Based on self-interference of two beam-split copies of the object's optical field with differential curvatures, the apparatus consists of a beam-splitter, a few mirrors and lenses, a piezo-actuator, and a color camera. No lasers or other special illuminations are used for recording or reconstruction. Color holographic images of daylight-illuminated outdoor scenes and a halogen lamp-illuminated toy figure are obtained. From a recorded hologram, images can be calculated, or numerically focused, at any distances for viewing.
通过数字全息技术可获得非相干照明下物体的全彩色三维图像。基于物体光场具有不同曲率的两个分束副本的自干涉，该装置由一个分束器、几块镜子和透镜、一个压电致动器以及一台彩色相机组成。记录或重建过程中不使用激光或其他特殊照明。获得了日光照明的户外场景和卤素灯照明的玩具人偶的彩色全息图像。从记录的全息图中，可以计算出图像，或在任何距离进行数值聚焦以供查看。
