If a plane-wave reference is used for recording and for reconstruction, then the reconstructed image will coincide with the magnified image of the object in amplitude, although the phase will contain the curvature due to the imaging lens. Alternatively, holographic interference of the object and the plane-wave reference can be formed first and its magnified image projected near the hologram plane...  2, record 1, English, - holographic%20interference

A nonlinear hologram enables to record the amplitude and phase of a waveform by spatially modulating the second order nonlinear coefficient, so that when a pump laser illuminates it, this waveform is reconstructed at the second harmonic frequency.  3, record 2, English, - nonlinear%20hologram

The image recorded on the holographic plate is called a hologram of the target, which carries both the amplitude and phase of the returned, scattered beam from the target. The first exposure of the holographic plate by the reference beam results in a reference hologram, while the second exposure by the returned beam imposes all changes of the target to the reference hologram.  2, record 3, English, - reference%20hologram

… the enormous amount of calculation in the generation of a complex hologram from a 3D [three-dimensional] object model consisting of many points is a huge challenge and the fast CGH [computer-generated holography] calculation problem has been investigated from different perspectives. Another major concern is that holographic display devices such as spatial light modulators(SLM) usually cannot display both the amplitude and phase part of a complex hologram simultaneously.  2, record 4, English, - complex%20hologram

Detour phase is the design principle … and is the core concept behind binary holograms, where the amplitude and the phase of the optical field are imposed by an array of apertures on an opaque screen. In a typical binary hologram, the dimension of each aperture sets the amount of light passing through it.  2, record 6, English, - binary%20hologram

[A hologram] transforms the reference wave into a facsimile of the object wave. This transformation is achieved practically [regardless of how] the intensity distribution in the fringe pattern is recorded, i. e. in the form of variations in the absorption or reflection coefficient(amplitude hologram) or in the refractive index or relief(phase hologram).  2, record 8, English, - amplitude%20hologram
