    Default Introduction to Holography - 1972

    Here's a 40 year old film that details the basic concepts of holography:

    It includes a close-up of an ancient HeNe (what the heck did they glue the Brewster windows to the tube with???), the demonstration of a hologram fragment's capability to reconstruct the entire original image, a circular hologram, and other neat stuff.

    That's Jung Teong (TJ) doing the demo, using the Gaertner holography kit equipment and a Holosonics He-Ne laser. It was probably Torrseal they used on the Brewster windows.
