Abstract: Apparatus and techniques for enhancing characteristics of electronic projection systems are detailed. Included among the techniques are both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. Pre-modulators and polarizing beam splitters also may be used as parts of the innovative systems.

Abstract: Apparatus and techniques for enhancing the dynamic range of electronic projection systems are detailed. Included among the techniques are pre-modulation, luminance compensation, and partial luminance compensation.

Abstract: A display system is disclosed that includes a light source, an integrator rod receiving a light beam from the light source and producing an integrated light beam, a beam splitting device splitting the integrated light beam into at least a first cone of light and a second cone of light, the cones of light having complementary intensity distributions, and at least a first spatial light modulator and a second spatial light modulator, wherein the first spatial light modulator is capable of selectively reflecting portions of the first cone of light in an ON direction and the second spatial light modulator is capable of selectively reflecting portions of the second cone of light in an ON direction. The display system further includes a combining device for combining the selectively reflected portions of the cones of light in the ON direction and projection optics for projecting the combined reflected cones of light.

Abstract: A common aperture, dual mode receiver for receiving and sensing radiation in the infra-red and microwave waveband comprises an input lens 1, a beamsplitter 2 which deflects microwave radiation and passes infra-red radiation to a microwave focussing sub-system (7, 8) and an infra-red focussing sub-system (3, 4, 5) respectively. The microwave sub-system includes an array of integrated antenna/mixer circuits positioned on the rear surface of the final lens 8.

Abstract: Receiver apparatus for receiving electromagnetic target radiation polarized in a first direction includes a dielectric lens having forward and rearward surfaces. The received target radiation is refracted at the forward surface and reflected by the rearward surface. An antenna array is disposed adjacent one of the forward and rearward surfaces for receiving (a) the target radiation reflected from the rearward surface, and (b) a local oscillator beam haivng a polarization direction which is orthogonal to the polarization direction of the target radiation received at the antenna array.
