Dye sensitized solar cell, AI filter, laser projection
This experiments explores the development of an optical communication interface as a component of a laser audio-visual art installation. The dye-sensitive solar cell was used as an photophone to convert the laser pattern into sound frequency. An artificial neural network was applied here to read the laser pattern and to produce interesting sounds.
One of the purposes of the experiment is to visualize the music spectrum; since the patterns of electrode of the dye-sensitive solar cells can be patterned by screen printing, it is interesting to find the mapping relationship between the laser projection and the electrode shapes.
A further exploration is to embed optical logic gates made of LCD layer in the current structure.
