Optical device suitable for illuminating the retina

A wearable virtual retinal display (VRD) device configured to be worn by a person;

• said VRD comprising a spectacle-like frame puttable on a head of said person;
• said spectacle-like frame carrying the following elements disposed along a laser beam:
• a. a laser light source configured for generating said laser beam at at least one radiation frequency;
• b. a microelectromechanical system (MEMS) configured for scanning said laser beam forming a laser radiation pattern to be projected to a person's retina;
• c. a lens;
• d. a selective reflector positionable in front of a person's eye;
• said selective reflector being configured for reflecting laser radiation at said at least one frequency;
• wherein said selective reflector has a piecewise-smooth reflective surface comprising a plurality of curvilinear selective reflecting elements, which in cooperation with said lens are configured for directing said laser radiation pattern onto a person's retina;
• said laser radiation pattern being scanned by said MEMS forms an image of an object of interest on said person's retina.
