31. Three plane waves with three equal angles formed by each two wave normal lines are recorded on hologram by three exposures.

32. Based on the theoretical analysis of the electron hologram, a spatial filtering method to avoid the overlap of the digital reconstructed images of electron hologram is proposed.

33. The resulting pattern was something he called a hologram after the Greek word holos meaning whole.

34. According to coupled wave theory, the volume hologram has a good property for light filtering and can be used as a kind of narrow-band filter.

35. An object image can be sampled first and then Fourier transformed by a computer, so that he complex amplitude and phase distribution can be encoded to form a computer-generated hologram (CGH).

36. Based on the coupled mode theory, the cross-talk noise in fractal multiplexed volume hologram is analyzed.

37. A new method for photorefractive multiplex hologram record was proposed.

38. Brightness, signal-to-noise ratio, viewing angle and monochromaticity are the main quality index of a hologram.

39. A research on aspheric surface testing by using a computer - generated hologram ( CGH ) on surface is presented.

40. In this paper, we propose a method for making a one-step lensless single-ray rainbow hologram, which makes the system structure simpler while the area of hologram larger.

41. Japanese scientists have created a hologram - or 3-dimensional image - that can be felt, Reuters reported.

42. In this paper, we also report a method of making multicolor reflection volume hologram in a plate through chemical treatment.

43. The critical part of this sight is a holographic optical elements combined with a lensless Fourier transform hologram and a holographic beam transformer.

44. The reconstructed hologram is obtained by applying inverse Fourier transform to encrypted hologram.

45. For example: caihong holographic radiotheraphy retarder ? ? s, multi - color, true color hologram computer - generated hologram.

46. The binary coding of cosine eliminates zeroth order diffraction theoretically, and can generate high pixel hologram.

47. Hologram label was applied to each Cloud's Raw anti - counterfeit purpose.

48. The Fourier transform realized by lensless Fourier hologram, and its application to 3-D measurement were studied. The experimental results were presented.

49. He brought up a hologram into the air over his computer terminal.

50. Volume holographic imaging (VHI) systems incorporate a volume hologram as one of the optical field processing elements in the system.

51. When reconstructed by white light source,(www.Sentencedict.com) the synthetic rainbow hologram is produced.

52. This can be done for laminating, glazing and hologram foil anti - false as cold - pressed.

53. Harvey: It's the latest visual software, it turns graphics into 3 D, almost a hologram. Very impressive.

54. Based on liquid crystal spatial light modulator and technology of computer-generated hologram, a new method of synthetic hologram display is proposed.

55. The worse the photopolymer shranks, the worse is the hologram reconstructed.

56. Grating, spatial light modulator, computer-generated hologram and film can be used as the filter.

57. This is because of the small recording area of the electronic record device (CCD), so the recorded digital hologram resolution is very low and the reconstruction image quality is affected greatly.

58. A hologram memory with high quality and high information storage density for analog information such as characters, lines and portraits has been made by sampling mesh and random phase shifter method.
