1) To make a hologram using an Argon laser (? max -40'. 0.488 ?m), the maximum angle between 4o". What is the requirement on the minimum obiective and reference beams is 6 resolution (or spatial frequeney) of the holographic recording film (fo -lines per mm)? When the hologram is reconstructed using a HeNe laser (?-0.633 um). Assume that Zo 10cm, zr = 2Zo, zp = 00, please compute virtual and real image locations (+2), the transversal and axial magnification (Mt and Ma) 2)
