Image projector with flexible reflective analog modulator

An image projector comprising:

• an optical apparatus for variably modifying the divergence of at least one reflected beam comprising at least one light source generating at least one input beam, a plurality of independently operated Flexible Reflective Analog Modulators (FRAMs) organized in at least one linear FRAM array, said linear FRAM array comprising at least one FRAM, each said FRAM generally comprising a flexible reflective member attached to a flat substrate by at least one leg extending outwardly therefrom, an electrode on said substrate and an electrode on said flexible reflective member thus forming a set of electrodes for applying an actuation voltage thereon, each said FRAM having a natural FRAM curvature in the absence of an actuation voltage applied thereon defined by a natural curvature of said respective flexible reflective member and a variable FRAM curvature adjusted by a range of actuation voltages applied thereon, said optical apparatus further comprising an illumination optics configured to address said linear FRAM array, said illumination optics focusing said input beam to produce at least one focused beam, said focused beam comprising a beam waist, said FRAM array having a FRAM array position either in front of, behind or at said beam waist and a FRAM array orientation such that said focused beam is reflected by said flexible reflective members of said FRAMs of said FRAM array to produce a plurality of reflected beams therefrom, each said reflected beam reflected by a respective FRAM of said FRAM array having a variable reflected beam divergence dependent on the respective FRAM position and the variable FRAM curvature of said respective FRAM, and thus on the range of actuation voltages applied thereon;
• a conversion optics for converting the variable reflected beam divergence of each said reflected beam into a variable reflected beam intensity, said linear FRAM array of independently operated FRAMs thus producing at least one line of variable intensity light dots;
• a scanning mechanism coupled to a projection optics, said scanning mechanism scanning through said at least one line of variable intensity light dots in a scanning direction perpendicular thereto, thus projecting, in conjunction with said projection optics, a bidimensional image.
