敏光通訊介面研發 Photophone based on dye sensitized solar cell
染敏太陽能、AI filter、雷射投影
此實驗計劃探索光通訊介面的研發，以做為雷射音像藝術裝置的構件。在這個實驗中染敏太陽能電池被用作光學麥克風，將投影到太陽能電池上的雷射圖形轉換成聲音頻率，光頻和聲頻是可以相互轉換的。
實驗裡利用了 Neutone 人工神經網絡來識別投影到電池上的雷射動畫圖案，來產生有趣的聲響。影片中比較了雷射原始波型和有透過人工神經網絡效果器兩組聲音的差別。
實驗的其中一個目的是將使音樂譜視化；由於染敏太陽能電池的圖案可以透過涓印技術自定義圖案，因此可以在形狀上找出與雷射圖形相匹配的關系。另一個目地是再更進一步的探索使用此光通訊介面來進行光學運算的可能性。由於染敏太陽能與 LCD 具有類似結構，未來有可能將由 LCD 製成的電晶體電路與具感光性的太陽能一體化。
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.
