摘要:
The present invention provides a sample inspection and quantitative imaging system and method for performing off-axis interferometric imaging while enabling to record off-axis holograms in an extended field of view (FOV) than possible using a given camera and imaging setup, and thus to enlarge (e.g. double, triple, or even more than this) the interferometric FOV, without changing the imaging parameters, such as the magnification and the resolution.
摘要:
Systems and methods for dynamic aperture holographic multiplexing are disclosed. One example process may include recording a set of holograms in a recording medium by varying both the reference beam angular aperture and the signal beam angular aperture. The angular aperture of the signal beam may be dynamically changed such that the closest edge of each signal beam angular aperture is selected to be a threshold angle different than the angular aperture of the reference beam used to record it. In some examples, the dynamic aperture holographic multiplexing process may include dynamic aperture equalization to reduce cross-talk, to improve error correction parity distribution for improved recovery transfer rate, to provide multiple locus aperture sharing for increased recording density, and to provide polarization multiplexed shared aperture multiplexing for increased transfer rate in both recording and recovery.
摘要:
A lens-free system for the three-dimensional imaging of objects contained within a sample places a sample holder between an image sensor and an illumination source, with the sample-sensor distance being much smaller than the sample-illumination source distance. Holographic images are taken at different angles as well as different lateral jogs within a single angle and are reconstructed into a three dimensional image of objects within the sample. The system may be a hand held, portable unit.

The present invention relates to a method and an apparatus for producing the raw material (46) used in producing black dye pigment. The invention further relates to a raw material (46) for producing black dye pigment as well as to the use of ash (20, 24, 26) separated from the raw synthetic gas (12, 14, 18) in the purification of the raw synthetic gas (12, 14, 18) generated in the gasification of a biomass (2, 4, 6) for producing black dye pigment.
摘要:
A multi-viewpoint image recording medium includes at least one main image recorded on the multi-viewpoint image recording medium and a plurality of sub-images, each having a display area smaller than a display area of the main image, recorded on the multi-viewpoint image recording medium. The main image and the plurality of sub-images are simultaneously displayed when the main image and the plurality of sub-images are reproduced. At least one of the plurality of sub-images changes in accordance with movement of a viewpoint.
