    Abstract: A lensless holographic imaging system having a holographic optical element includes: a coherent light source for outputting a first light beam and a second light beam, wherein the first light beam irradiates a first inspection plane to form first object-diffracted light; a light modulator for modulating the second light beam into reading light having a specific wavefront; a multiplexed holographic optical element, wherein the first object-diffracted light passes through the multiplexed holographic optical element, and the reading light is input into the multiplexed holographic optical element to generate a diffracted light beam as system reference light; and an image capture device for reading at least one interference signal generated by interference between the first object-diffracted light and the system reference light. The lensless holographic imaging system has a relatively small volume and relatively high diffraction efficiency.

    Abstract: A detecting system for detecting an under-test light of an under-test object includes a light spatial distribution unit, a chromatic-dispersion light-splitting unit and a detecting unit. The light spatial distribution unit is disposed on a side of the under-test object to receive the under-test light and form a plurality of point light sources. The chromatic-dispersion light-splitting unit is disposed on a side of the light spatial distribution unit to receive the point light sources and produce a light-splitting signal. The detecting unit is disposed on a side of the chromatic-dispersion light-splitting unit to receive the light-splitting signal and produce an optical field distribution of the under-test light.

    Abstract: The present invention provides a method for repairing incomplete 3D depth image using 2D image information. The method includes the following steps: obtaining 2D image information and 3D depth image information; dividing 2D image information into 2D reconstruction blocks and 2D reconstruction boundaries, and corresponding to 3D reconstruction of blocks and 3D reconstruction boundaries; analyzing each 3D reconstruction block, partitioning into residual-surface blocks and repaired blocks; and proceeding at least one 3D image reconstruction, which extends with the initial depth value of the 3D depth image of each of the residual-surface block and covers all the corresponding repaired block to form a repair block and to achieve the purpose of repairing incomplete 3D depth images using 2D image information.

    Abstract: A diffractive optical assembly includes an input coupler, an output coupler, and an image source. The output coupler is next to the input coupler. One of the input coupler and the output coupler has a most critical holographic optical element (HOE), and another one has a diffractive optical element (DOE). Bragg condition of the most critical HOE is more sensitive than Bragg condition of the DOE. The image source is configured to generate image light that is incident to the input coupler then propagates to the output coupler. The image light has incident angles to the input coupler and wavelengths corresponding to the incident angles. The wavelengths of the image light on the image source have a two-dimensional spatial distribution, such that relationships between the incident angles and the wavelengths of the image light comply with Bragg selectivity of the most critical HOE.

    Abstract: A holographic device includes a holographic storage device, a shearing interferometer, and an optical receiver. The holographic storage device is configured to provide a disk with a reading light beam to make the reading light beam become a diffracted light beam after the reading light beam is diffracted in the disk. The shearing interferometer is configured to receive the diffracted light beam and to transform the diffracted light beam into a first light beam and a second light beam. The optical receiver is configured to receive the first light beam and the second light beam provided by the shearing interferometer.
