A method of correcting a holographic image, a processing device, a dark field digital holographic microscope, a metrology apparatus and an inspection apparatus. The method includes obtaining a holographic image; determining at least one attenuation function due to motion blur from the holographic image; and correcting the holographic image, or a portion thereof, using the at least one attenuation function.

Portable common path shearing interferometry-based holographic microscopy systems are disclosed herein. In one embodiment, a system is configured for positioning a laser light source, a sample holder, a microscope objective lens, a shear plate and the imaging device in a common path shearing interferometry configuration. In some embodiments, the systems are relatively small and lightweight and exhibit good temporal stability. In one embodiment, a system for automatic cell identification and visualization using digital holographic microscopy using an augmented reality display device can include an imaging device mounted to an augmented reality display device, configured to capture one or more images of the hologram of the sample disposed on the sample holder illuminated by a beam. The augmented reality display device can include a display and can be configured to render a pseudo-colored 3D visualization of the sample and information associated with the sample, on the display.

An information processing apparatus includes a controller that controls formation of an image to be formed in air so that the image and a user do not overlap each other in a space.

An image display device includes image cells arranged two-dimensionally. Each image cell has a hologram layer. The hologram layer includes a diffraction grating in which a one-dimensional grating pattern extending in a first direction is repeated in a second direction perpendicular to the first direction. Among the plurality of image cells, two or more image cells that are in a row in the second direction and correlated to one color constitute one image cell group. The image cell group includes a section in which the spatial frequency of the diffraction grating is proportionately small as the distance in the second direction from one end of the image cell group increases such that, while a viewpoint is positioned at a predetermined angle relative to an image display device, the two or more image cells constituting the image cell group display the same color as each other.

Disclosed is a hologram stage setting which is configured to apply a net screen of a grid network structure coated by a ceramic ball lens on the front part of a stage and directly project images, thereby enabling performance without specific limits on general multi-purpose stages instead of special stages, solving high cost problems caused by using a conventional foil screen, implementing high-resolution images, enhancing durability, and performing easy maintenance and repair. The hologram stage setting includes: a rear screen which is installed on the rear part of a stage to display a rear background image; a lower screen which is installed on the lower part of the stage to display a lower background image; a front screen which is installed on the front part of the stage to display a front hologram image; and a front hologram image projector which generates and projects the front hologram image.

A hologram generation apparatus includes an LCOS, an LCOS display control unit configured to form a partial hologram generation display area and positioning hologram generation display areas on a display surface of the LCOS, an object light optical system configured to apply object light onto a recording medium and generate a partial hologram and positioning holograms, the object light being generated by the partial hologram generation display area and the positioning hologram generation display areas, and a position control unit configured to determine a position of an partial hologram to be generated next based on positions of the generated positioning holograms.

Processes and systems are described that can produce images including both three dimensional holographic images and two dimensional variable data, which can provide personalized security features in a document. A photosensitive film can be pressed against a first reflective optical device. A laser beam can be directed through a selected first area of the photosensitive film onto the first reflective optical device to produce a three dimensional holographic image in the photosensitive film. A previously masked second area of the photosensitive film can be pressed against a second reflective optical device. The laser beam can project an image constructed by a spatial light modulator and can be directed through the second area of the photosensitive film onto the second reflective optical device to produce a two dimensional image in the second area. During the process, the web tension of the photosensitive film is controlled.
