Hologram Basics:
• A laser-generated image with three-dimensional properties
• Created by capturing the intensity and phase information produced by the interference of two (or more) beams of light
• 2 basic types of holograms: Transmission and Reflective
Reference Beam
Object Beam
Interference Pattern
Transmission Type Holograms
• the holographic plate is placed behind the object and laser, or to the side at 45 degree angle
• Must be viewed with laser light
• Captures an image much bigger than the holographic plate
• Allows an image can be projected onto a screen or other surface with a laser
Litiholo Setup – Instant Hologram Film
White Light Reflection Type Holograms
• the holographic plate is placed between the object and laser
• can be viewed with “white” incandescent light (or the sun)
Contact Style Exposure
Integraf Setup – “wet” process Hologram Film
Hologram Tips:
• Follow all printed instructions
• Insure proper and safe use of all laser equipment
• Lasers should be run for approximately 5 minutes before attempting any exposure
• Any kind of vibration or movement (this includes talking which produces sound wave vibrations) will destroy the interference pattern and leave you with a blank holographic plate
• Holographic equipment and plates are expensive $$$, if in doubt about any step in the process….ask!!!
