Lens with SLM
First Claim
Patent Images
1. A lens, comprising:
- a lens body, comprising a transparent optical material having a predetermined refractive power; and
a focal modulation device fixed to the lens body and comprising;
a semiconductor substrate;
a spatial light modulator (SLM) formed on the substrate so as to permit light collected by the lens body to pass through the SLM;
a control circuit, which is formed on the substrate and is coupled to actuate the SLM so as to modulate the refractive power that is applied to the light passing through the SLM; and
a photovoltaic cell, which is formed on the substrate and is coupled to provide electrical power to the control circuit responsively to light that is incident on the photovoltaic cell.

Abstract
Apparatus for enhancing vision of a user includes a focal modulation device (22), which is adapted to focus light from objects in a field of view of the user onto the retina while alternating between at least first and second focal states that are characterized by different, respective first and second focal depths, at a rate in excess of a flicker-fusion frequency of the user.
