    摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.

    摘要： In a method for driving a micro mirror such as MEMS mirror and a display apparatus using the method, there are provided a mirror driving unit for driving the micro mirror which operates in a resonant mode and a nonresonant mode, a driving-condition setting unit for setting a mirror driving condition, a switching unit for switching on/off a mirror driving signal in the nonresonant mode, and a look-up table for indicating the relationship of a mirror response with respect to the driving condition already known in advance. The switching unit controls the transmission of the nonresonant-mode mirror driving signal while grasping the mirror response state with respect to the mirror driving signal, thereby finely increasing and decreasing a driving torque for the micro mirror. This fine increase and decrease allows the micro mirror to be fluctuated stably, and a further enhancement in the fluctuation rate.
