提出了一种利用激光二极管电流调制的波长扫描数字全息技术。通过波长扫描扫描全息图的相位,记录一系列全息图。通过对全息图的每个像素点进行时间频率分析,从记录的全息图中提取目标波分量。所提出的技术使我们能够使用简单且经济有效的光学装置将大型物体记录为数字全息图。
Wavelength scanning digital holography using laser diode current modulation is presented. A series of holograms are recorded while the phase of hologram is swept through wavelength scanning. The object wave component is extracted from recorded holograms by applying temporal frequency analysis to each pixel of the holograms. The proposed technique allows us to record a large object as digital hologram using simple and cost effective optical setup.
