MRISAR's Interactive Photonic Spectrum Exhibit
Directions: Slowly bring your hand down over the bottom cylinders. When you get close to them, they will trigger lights in the upper cylinders and sounds. Each cylinder triggers a different sound tone and light spectrum, or when triggered in combination they will produce much deeper tones and light variations.
This exhibit utilizes a series of photo resistors to control a sound synthesizer. The sound synthesizer consists of two oscillators which work in unison by resonating at specific intervals dependent on the signals from the sensors. The exhibit features acrylic inside of aluminum columns to house the sensors and lights that react to the presence of a user’s hands.
The geometry of the exhibit accents an otherworldly appeal that will excite the visitor’s interest. One or two people can operate the Photonic Spectrum at a time. To use the exhibit a visitor needs to gesture with their hands between the columns. Depending on the position of their hands the exhibit can produce sounds ranging from the high frequency range and down to a low rumbling bass. The exhibit demonstrates sound synthesis, sensors and light control. The overall size of the exhibit is approximately 72” high by 36” wide by 33” deep.
A Solar powered version is available at no additional cost. Many case colors are available to compliment your current exhibit selection.
