3201H: Honors Holography 1

Laboratory Procedures
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:

1. Diffraction Grating

2. One-step Rainbow Hologram

3. Split Beam Transmission Hologram

4. Single Beam Reflection Hologram

5. Mat Cutting Procedure

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.

     - On-time attendance (unexcused absences will adversely affect your grade)
     - Notebook and/or sketchbook
     - Lock for lab locker

Still-Life Assignment

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.

Things to remember:

Materials which give interesting textures include rice, powder and sand.

Silver, bright white, yellow show up best. Dark colors disappear. Transparent materials like glass and plastic work well.
shadows and light:

The best way to look at an object or 'Still-Life' is in the laser light. Remain flexible and open-minded about your 'Still-Life' so that you can make adjustments (move objects within the scene, add or delete objects, etc.) in order to obtain the best possible lighting.
content or meaning:

Think about creating a mood or feeling with your 'Still-Life', but avoid obvious, trite, or overused subject matter.

Double check all components for stability. Unstable objects in your scene may move during exposure, creating `black holes'. Unstable components may wipe out the scene entirely.

Still-Life Schedule
     - Sketches will be due the 10th week of class.
     - Work in progress will be discussed during the 10th week of class.
     - The finished still life will be due during the 10th week of class.

Relief-Sculpture Assignment

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.

Relief-Sculpture Schedule
     - Sketches will be due the 12th week of class.
     - Work in progress will be discussed during the 12th week of class.
     - The finished relief sculpture will be due during the 13th week of class.
