Projektbeschreibung
This project is collaboration with the Laboratory for Microactuators in which we fabricate and evaluate an optofluidic scannable slit for a hyperspectral system .
The design contains no moving mechanical parts and functions by manipulation of liquid interfaces between two aqueous ink droplets in an ambient of silicone oil by means of of electrowetting-on-dielectric (EWOD). The developed device can form a 100 µm wide slit that is scannable over a transparent aperture of size 1500 µm x 1500 µm in 15 discrete steps. Switching time between adjacent slit positions is estimated to be less than 120 ms.
