    摘要： 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. A light wave (cj) of the illumination light (Qj) is separated from the light wave (hj), and using its phase component (ξj=cj/|cj|), a phase adjustment reconstruction light wave is derived and added up as (HP=Σhj/ξj), and an object image (SP=|HP|2) is reconstructed.

    摘要： Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device 1 comprises a light source 10, a first modulator 20, a second modulator 30, a lens 40, a beam splitter 41, a photodetector 46, and an arithmetic unit 50. The lens 40 receives scattered light generated by a moving object 2 and forms a Fourier transform image of the object 2. The photodetector 46 outputs data representing a sum in a v direction of data temporally changing at a frequency corresponding to a Doppler shift frequency of the light having reached each position on a light-receiving surface through the lens 40 at each position in a u direction at each time. The arithmetic unit 50 obtains an image of the object 2 according to the output of the photodetector 46.

    摘要： A high resolution 3-D holographic camera. A reference spot on a target is illuminated by three spatially separated beamlets (simultaneously produced from a single laser beam), producing a lateral shear of a wavefront on the target. The camera measures the resulting reflected speckle intensity pattern which are related the gradient of the interfered complex fields. At the same time a flood beam illuminates the entire target and reflected speckle is also recorded by the same camera to provide the necessary object spatial frequencies. The illumination patterns are sequenced in time, stepping through offset phase shifts to provide data necessary to reconstruct an image of the target from the recorded reflected light. The reference spot phase and amplitude are then reconstructed, and the reference spot's complex field is then digitally interfered with the flood illuminated speckle field by use of a special algorithm. In order to obtain a high resolution 3D image of the target, a second measurement is acquired with the laser beam slightly shifted in frequency to second color.
