Laserfilm was a videodisc format developed by McDonnell-Douglas in 1984 that was a transmissive laser-based playback medium (unlike it's competitor, laserdisc, which was a reflective system). It worked by having the laser to shine through one side of the disc to a receiving sensor on the other side, where the beam of the laser would be interrupted by a spiral of small dots on the disc. This would in turn modulate the laser beam to represent the video and audio information, which was then interpreted by the receiving sensor receiving the beam on the other side.

The disc was made out of ordinary photographic film, which was mounted in a caddy for playback, much like the RCA Selectavision CED videodisc system. SelectaVision was originally the name for a video playback system developed by RCA using specialized disc-based media, in which video and audio could be played back on a TV using a special analog needle and groove system similar to phonograph records. ...
Laserfilm players were chiefly manufactured by McDonnell-Douglas, and wasn't marketed successfully outside of the company. However, the format was employed for use in their flight simulators, by linking several players together.
The installation is based on the idea of applying a new technological advance from the field of optics [diffractive elements] to film as a medium.
The simple optical construction of Laserfilm, on the other hand, involving nothing more than a data carrier and a laser as its light source, makes it possible to directly project a film without needing to resort to further technical.
The film is mounted on a glass disc held in the centre of a freely swinging pendulum suspended from the ceiling.
