How Do You Make A Simple Hologram?
Holography is a technique that can capture an image by recording the light scattered from it. A holographic image, called a hologram, appears 3-D, changing along with the position and orientation of the viewer. Making your own simple hologram requires some equipment and patience, but it is a great experiment to do at home. Step 1 Place your hologram subject on a sturdy table. Use a mouse pad or other non-skid surface to reduce any vibrations. Step 2 Place your laser pointer about 30 cm away from the subject. Attach it to a clothespin and secure the end of the clothespin in a cup of sand. Step 3 Take off the adjustable lens and position the laser so that the beam can spread out horizontally in an elliptical shape. Step 4 Locate the subject completely in the beam of the laser. Step 5 Turn off the lights. Make sure that no direct light will reach the holography system. Step 6 Set a book between the laser beam and the subject to act like a camera shutter. Step 7 Lean one holographic film p
