摘要： A 2D image display apparatus using a laser light source. By controlling the timing of a scan by a beam scan portion in response to the characteristic of a laser light source and by setting a light emitting time of the laser light source to an integral multiple of a scan cycle of the beam scan portion, it is possible to illuminate a spatial light modulator homogeneously with a laser beam. It is thus possible to display an image at high accuracy without causing a bright line, irregularities in brightness, and contrast deterioration.

摘要： A compact multi-band hybrid ring (rat-race) coupler utilizing a ring of composite right-handed and left-handed (CRLH) transmission lines (TLs) and multiple ports, provides miniaturization and the ability to operate at arbitrary frequency bands unlike conventional couplers. The hybrid ring is made compact, such as by constraining phase delay contributions |φ1|, |φ2|≦270°. The coupler can be used in many applications, for example as a mode decoupling network in a dual-band front-end MIMO system. The inclusion of a CRLH delay line is also described which alters the phase relationship of the signals and is particularly well suited for extending pattern diversity in response to frequency.
