Problem 1

Assumed that the reflectivity of the object is 70\%, calculate the visibility for the setup given in Fig. 10.1. The distance object / holographic plate is $15 \mathrm{~cm}$, the plate is $10 \times 10 \mathrm{~cm}$.

Problem 2

Illuminating the hologram with the reference wave or with the object wave reconstructs the object wave and the reference wave, respectively. What is the reason for the always observed low intensity of the reconstructed reference wave (Figs. 10.1 and 10.2)?

Problem 3

If the area from the first beam splitter in Fig. 10.2 to the object is considered, the setup for the white light reflection hologram is a very symmetrical parallelogram. This is true for the left illumination wave and the reference wave. The right illumination wave is geometrical of the same length than the left one. What is the maximum possible distance between the object and the holographic plate? If the distance has to be larger than the maximum value, what measures can be taken to correct the setup in Fig. 10.2?

Problem 4

The white light reflection hologram (Fig. 10.2) is reconstructed with a white light point source at the same position than the pinhole of the reference wave $\left(z_r=z_c=100 \mathrm{~cm}\right)$. The distance of the object was $z_o=15 \mathrm{~cm}$. The shrinkage of the emulsion is $20 \%$. The reconstruction wavelength moved from $632.8 \mathrm{~nm}$ to $500 \mathrm{~nm}$. What is the lateral magnification $V_{\text {lat }}$ of the virtual and the real image? To view the real image, the hologram is rotated by $180^{\circ}$.
