Exempel på holography

• The time difference between both diodes indicated the time of the holography picture related to the arrival of the laser pulse at the target.

• Holography offers the potential for large field and high resolution.

• The off-axis holography technique has the advantage that the reconstructed beam and the image are separate.

• In the second method we have used off-axis holography to record the forward scattering only.

• 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.

• In the first method we have used forward and backward scattering simultaneously with a single reference beam and recorded both cases of off-axis holography on the same film.

• I do not think it is fair to say that holography is quite akin to photography in that sense.

• It assumes a relationship between photography and holography which may not remain the same.

• Gratings which modulate the phase rather than the amplitude of the incident light are also produced, frequently using holography.

• It was not until 1982 that he began to work in holography, using artisanal methods.

• This effect has been used to demonstrate atomic holography, and it may allow the construction of an atom probe imaging system with nanometer resolution.

• However, competing theories explain the results of interferometric holography tests differently.

• He instructs people new to holography how to make simple holograms, for example by using a laser pointer.

• The above properties of holograms guided the development and are the rationale behind the functional holography method presented here.

• Holography allows users to modify the appearance of their dwellings or selves into more appealing facades.
