Structural association of cells with optical devices, e.g. reflectors or illuminating devices

Full Title

Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour (G02F1/29, G02F1/35 take precedence) > based on translational movement of particles in a fluid under the influence of an applied field > Constructional details > Structural association of cells with optical devices, e.g. reflectors or illuminating devices
