摘要:
A Micro-Electro-Mechanical Systems (MEMS) device for actuating a gimbaled element, the device comprising a symmetric electromagnetic actuator for actuating one degree of freedom (DOF) and a symmetric electrostatic actuator for actuating the second degree of freedom.
摘要:
An image display system including an image projector operative to receive image content and to project, accordingly, an output image onto a display surface, a sensor generating a sensor output pertinent to operation of the image projector, thereby to generate a sensor output; and an image projector feedback unit operative to control the image projector, responsive to the sensor output.
摘要:
A system and method for using a laser, including using a coherent light source to generate a beam having a dominant wavelength wl; and providing along the beam's light path, at least one optical element having a surface upon which the beam impinges, whose roughness is between D and 1/2wl- D where D is double the tolerance of the laser's dominant wavelength.
摘要:
A method for protecting an optical MEMS device, including providing an optical MEMS device defining a field of view and including layers which define a main plane; and forming a protective element, constructed and operative for at least partly covering the optical MEMS device, from an optical structural material and wherein the protective element includes a planar portion tilted with respect to said main plane via which a majority of light energy directed toward said main plane must pass.
