Rebirth of Liquid Crystals for Sensoric Applications: Environmental and Gas Sensors

Figure 10

Idealized fingerprint structure, view from the top (compared to the central part of Figure 7). Elongated cylinders represent predominant molecular orientation. and are directions of polarization of incoming and outcoming light. Bright yellow lines correspond to brighter areas in fingerprint structure; dark blue lines correspond to darker areas with homeotropic molecular orientation.
