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.

多波长复用相移非相干彩色数字全息

我们提出了多波长复用相移非相干彩色数字全息技术。在这种技术中,单色图像传感器记录波长复用的,相移的和不相干的全息图,而相移干涉技术则从多个记录的全息图中有选择地提取多个波长的物波。包含多个波长的空间非相干光照亮对象,并且无需使用任何波长滤镜即可同时获得多波长非相干对象波。实验证明了其对透明和反射物体的有效性。
