In this work, we demonstrate single-shot, simultaneous recording and subsequent retrieval of one incoherent and two holographic (intensity and phase) images from the same camera frame. Demultiplexing of incoherent and holographic signals in the spatial frequency domain is made possible by carrier frequency modulation and spatial oversampling intrinsic to the off-axis digital holographic configuration. In particular, we show applications to combined fluorescence and digital holographic microscopy, as well as combined bright field and holographic second harmonic generation microscopy.
在这项工作中，我们演示了从同一场相机帧中单次、同时记录和随后检索一个非相干和两个全息（强度和相位）图像。通过载波频率调制和离轴数字全息配置固有的空间过采样，在空间频率域中实现了非相干和全息信号的解复用。特别地，我们展示了在组合荧光和数字全息显微镜以及组合明场和全息二次谐波产生显微镜中的应用。
