This semester you will make four different types of holograms and learn how to present them. Below we list the laboratory procedures for each hologram:
Instructions to Remember
- Follow all lab procedures as instructed.
- Sign up for lab time in advance.
- Treat all equipment with respect. Do not move components except as instructed.
- Never touch front surface mirrors or other optical components. This may harm them.
- Never attempt to clean mirrors or lenses. This will ruin them.
- Clean up dark room chemicals and trays before leaving.
- Always turn off the laser and safe lights when leaving.
- Place your Name, Title, and Date on your work with an acetate marker.
Diode Laser Assignment
Here you will find a list of various and helpful pdf files available for your download.
Create a Still-Life as the subject for a transmission hologram. The created Still Life must be viewable in laser light through a 5" x 7" film holder. In designing your Still Life remember to include the ground plane, depth (about 6"-10"), and complete 3-D viewing including up and down. Materials which have worked well in the past include clay, wood, plaster, metal and glass.
You may carve or cast your Still-Life with Sculpey or other brand of modeling clay or with Geltrate. You may carve balsa wood, plaster, etc. You may fashion metal into shapes or assemble found items with hot glue. You may wish to paint your Still-Life to obtain the proper beam ratio.
Construct one (or more) small Relief-Sculptures as the subject matter for a reflection hologram. The relief should not exceed 1.5" in depth. The height and width should be proportional to the size of the film you are using, usually 4" x 5". The 'Relief-Sculpture' should be flat on one side, making it easier to stabilize for holographic shooting.
You may build, carve or cast your relief form in any suitably stable material such as wood, metal, plastic, plaster etc. The relief should be as stable as possible, solidly constructed in a rigid material.
Your relief should reflect and diffuse light well. Therefore it should be lightly colored or metallic overall. You may wish to paint some or all of the sculpture to brighten it. You should avoid highly polished, mirror-like surfaces as they may be too reflective, causing the film to "burn-in" from overexposure in some regions.
