FIG. 7.19 (a) Vertical pendulum tilt sensor ( Dong et al., 2005 ) with three fiber Bragg gratings attached to three cantilevers. A tilt of the pendulum leads to bending of the cantilevers depending on the direction of the tilt. This leads the attached fiber Bragg grating to strain and change its reflection spectrum. (b) Schematic of a MEMS ring laser gyroscope with movable mirrors and lens. ( Hashimoto et al., 2009 ). (c) Schematic of a passive resonant optical gyroscope using a fiber ring. The phase modulators are driven by antiphase triangular waves to reduce parasitic effects and allow the readout of Sagnac phase shift as amplitude at photodetector ( Jin et al., 2007 ). More about this image found in (a) Vertical pendulum tilt sensor ( Dong et al., 2005 ) wi...

On that note, our viewpoint differs from Wiliam (2006 , 2007 ) and Black and Wiliam (2009) , who argued that the beneficiaries of feedback did not need to be the same as those from whom information was collected. Our theoretical accounts of formative assessment provide a new lens to examine interactive...
