Problem 2. a laser with an output wavelength 633 nm and a spectral width 0.005 nm is used to record a hologram. the refractive index of the holographic recording material is n 1.5. if the angle between the object and the reference beam is 30 degree as shown in the below figure and the maximum allowed vibration is one fourth of the period of holographic fringe, calculate (a) what is the definition of the hologram? (b) the maximal allowed vibration during the holographic recording process. (c) the maximal allowed optical path difference between the object and reference beams. (d) if this is a thin phase hologram, what is the highest diffraction efficieney of this hologram? tiitliellzzi holographic plate
