| 释义 | hologram noun[ C ] uk /ˈhɒl.ə.ɡræm/ us /ˈhɑː.lə.ɡræm/ a special type of photograph or image made with a laser in which the objects shown look solid, as if they are real, rather than flat全息图，全息影像 R_Type/iStock/Getty Images Plus/GettyImages Photography aerial photograph airbrush analogue aperture backlight backlighting expose ghost image ghosting glossy golden hour grainy halation pap photojournalist photoshoot pic picture PillCam projection hologram | American Dictionaryhologram noun[ C ] us/ˈhɑl·əˌɡræm, ˈhoʊ·lə-/ an image made with a laser beam, in which the objects shown look like they have depth rather than appearing flat and can seem to move Examples of hologramhologram After the recording and the developing, the hologram was returned to the second holder and moved into the laser beam line. For the recording of the hologram, the plate was placed behind the shutter and this assembly was moved into the laser beam line. Now snip off a comparably sized piece from a diffraction image hologram containing the same chair information. Self-adaptive solid-state oscillator formed by dynamic gain-gratings holograms. Two photodiodes measured the time difference between the main laser pulse, generating the shock wave, and the diagnostic laser producing the hologram. That is because any part of the hologram relates to the whole of the real space image. Of particular significance is the proposal that such memories are not simply stored like letters in a mailbox or images distributed throughout a hologram. Therefore, only forward or backward scattering of the light illuminating the body will produce a hologram of the moving object. The use of diffractive optics in that area is known to almost everyone from the little holograms on credit cards. The first method was used for getting two holograms at the same time on the same medium, using both backward and forward scattering, with one reference beam. The "projection hologram" is, of course, only an analogy, but it is useful in that it shares some of the apparently puzzling features of conscious experiences. As a wave traveling through a hologram specifies a virtual image, this brain-supported wave specifies a time-scaled, virtual subset of the field related to the body's action. Three configurations of off-axis holography were applied in our experiments: holograms based on back scattering, holograms based on forward scattering, and holograms using both backward and forward scattering. One does not need to wait for a printout of the drawing, but this really has nothing to do with photographs or holograms. From the Hansard archive Example from the Hansard archive.
