We propose multiwavelength-multiplexed phase-shifting incoherent color digital holography. In this technique, a monochrome image sensor records wavelength-multiplexed, phase-shifted, and incoherent holograms, and a phase-shifting interferometry technique selectively extracts object waves at multiple wavelengths from the several recorded holograms. Spatially incoherent light that contains multiple wavelengths illuminates objects, and multiwavelength-incoherent object waves are simultaneously obtained without using any wavelength filters. Its effectiveness is experimentally demonstrated for transparent and reflective objects.
我们提出了多波长复用相移非相干彩色数字全息术。在该技术中,单色图像传感器记录波长复用、相移和非相干全息图,并且相移干涉测量技术从几个记录的全息图中选择性地提取多个波长的物波。包含多个波长的空间非相干光照射物体,并且无需使用任何波长滤波器即可同时获得多波长非相干物波。我们通过实验证明了该技术对透明和反射物体的有效性。
