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!!!
