Image display apparatus


An image display apparatus is provided, which uses a light deflection element capable of deflecting incident light so as to follow the position of an observer, and suppressing reduction in the intensity of light reaching eyes of the observer, regardless of the position of the observer. The light deflection element according to the present disclosure is configured to deflect incident light, and includes: a first optical element that deflects incident light; a second optical element that changes a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a first electrode provided on the first optical element side; a plurality of second electrodes provided on the second optical element side; and a control section that controls the voltage applied to the second optical element..

Sensor for combined temperature, pressure, and refractive index detection


A sensor (1) has a light conductor (2) having a grating (fbg), a cavity (5), and a transparent cavity end wall (4), a light emitter for directing light through the conductor, and a light detector for detecting reflected light, and a processor. The processor is adapted to analyse light reflected due to the grating (fbg, 6) to determine an indication of temperature, light reflected from the end (7) of the cavity (5) to determine an indication of pressure, and also light reflected from the outer surface (8) of the cavity wall (4) to determine an indication of refractive index of a medium outside said cavity wall.
