REFRACTIVE INDEX CONTINUUM STRUCTURE AND DEVICE, AND ENERGY CONCENTRATION TEST SYSTEM

WIPO Patent Application WO/2021/179121

A1

The present invention relates to the field of beam propagation, and relates in particular to a refractive index continuum structure and device, and an energy concentration test system. The refractive index continuum structure comprises: a light-transmitting substrate 110; a first layer that is provided on an incident surface of the light-transmitting substrate 110 and has a gradient refractive index; a second layer that is provided on an exit surface of the light-transmitting substrate 110 and has a gradient refractive index; and a thermochromic layer that is provided on an exit surface of the second layer. The beneficial effect of the present invention is that, compared with the existing technology, the present invention designs a refractive index continuum structure (ICS) composed of two gradient refractive index layers and a thermochromic layer so that light can carry out light bending and energy concentration during the propagation thereof, and incident beams can be effectively concentrated in one direction regardless of angle and polarization. In addition, the effect of energy concentration is very intuitive, and the energy concentration efficiency can be automatically adjusted by means of environmental temperature.
