Patent number: 10156829Abstract: The present invention can realize both a transmission type and a reflection type, and provides a holographic microscope which can exceed the resolution of the conventional optical microscope, a hologram data acquisition method for a high-resolution image, and a high-resolution hologram image reconstruction method. In-line spherical wave reference light (L) is recorded in a hologram (ILR) using spherical wave reference light (R), and an object light (Oj) and an illumination light (Qj) are recorded in a hologram (IjOQR) using a spherical wave reference light (R) by illuminating the object with an illumination light (Qj, j=1, . . . , N) which is changed its incident direction. From those holograms, a hologram (JjOQL), from which the component of the reference light (R) is removed, is generated, and from the hologram, a light wave (hj) is generated.Type: GrantFiled: October 28, 2014Date of Patent: December 18, 2018Assignee: University of HyogoInventor: Kunihiro Sato
