Holography

• Images to a point with no aberrations
• Aberration control possible
• Highly dispersive
• Optical power on a flat surface
• Off-axis geometry
• Can be transmissive or reflective
• Narrowband response
• Can be replicated

• High dispersion
• Large aberration away from construction conditions
• Efficient over small wavelength band
• Limited design flexibility
• Difficulty with control of holographic emulsions
