This semester you will make three 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.
Construct one (or more) small Glass-Sculptures as the subject matter for a (back-lit) reflection hologram. The sculpture should not exceed 6" in depth. The height and width should be proportional to the size of the film you are using, usually 5" x 7". The Glass-Sculpture will be mounted on its side; thus it should be flat on one side, making it easier to stabilize for holographic shooting.
You may carve or cast additional parts of the sculpture in any suitably stable material such as wood, metal, plaster, etc. The sculpture should be as stable as possible, solidly constructed in a rigid material.
If parts of your sculpture are designed to reflect or diffuse light you may wish to paint these parts white to brighten them or black to darken them. Color to these parts may be added in the final piece by chemically treating the film with TEA before exposure. 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.
Schedule: Due during the 2nd week of class.
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 been shown to work well in the past include clay, wood, plaster, metal and glass.
You may carve or cast your Still-Life with Sculpty 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.
Consider the notion of Multiple Images or animation as the subject for a transmission hologram. In this type of hologram as the viewer moves different views will become apparent giving a causal effect between the viewers motion and time. This type of hologram may be made with real objects which include a ground plane, depth (about 6"-10"), and complete 3-D viewing, or with photographs, slides or computer generated objects. Consider the possibility of holo-poems and morphed images.
You will need up to 24 images of an object or objects in 1 degree steps. This may be accomplished using photographs, slides, or by generating and rendering the images on a computer. You may use a smaller number of images and a morphing program to generate the missing views.
Schedule: Extra Credit.
