Abstract
Sensors operate by resolving changes in orientation of a wavelength dependent structure with respect to a reference direction determined by an incident light beam, resulting in very high sensitivity and dynamic range. Said sensors are wavelength encoded, can be multiplexed in a single light path such as an optical fiber, yet are decoupled mechanically from the fiber, resulting in high stability.
