  • Publication number: 20090091730
    Abstract: A spatial light modulation unit can be arranged in an optical system and can be arranged along an optical axis of the optical system. The spatial light modulation unit includes a first folding surface which folds light incident in parallel with the optical axis of the optical system; a reflective spatial light modulator which folds the light folded on the first folding surface; and a second folding surface which folds the light folded on the spatial light modulator, to emit the light into the optical system. The spatial light modulator applies spatial modulation to the light, according to a position where the light folded on the first folding surface is incident to the spatial light modulator.

  • Patent number: 7515248
    Abstract: An illumination optical system for, when installed in an exposure system, realizing a suitable illumination condition by varying the polarized state of the illumination light according to the pattern characteristics of the mask while suppressing the loss of the intensity of the light. The illumination optical system has a light source unit for supplying a linearly polarized light for illuminating surfaces to be illuminated therewith, and a polarized state changing device for changing the polarized state of the illuminating light from a predetermined polarized state to a nonpolarized state and vice versa.

  • Patent number: 7516008
    Abstract: This vehicle motion control apparatus obtains a yaw rate deviation by subtracting the value (actual-yaw-rate-after-low-pass-filter-process Yrfilter), which is obtained by providing with a time constant ?1 (>?2) the low-pass filter process to the actual yaw rate Yr obtained from the yaw rate sensor incorporated in the HU, from the value (turning-angle-yaw-rate-after-low-pass-filter-process Yrtfilter) obtained by providing with the time constant ?2 the low-pass filter process to the turning angle yaw rate Yrt obtained on the basis of the actual steering angle obtained from the steering angle sensor, which is provided separate from the hydraulic unit HU. When this yaw rate deviation exceeds the threshold value Yrth (time t3?), this apparatus starts an under-steer suppression control.

  • Publication number: 20080240182
    Abstract: A new and useful attenuating device and method for attenuating a polarized laser beam is provided. At least one attenuating optic is located along, and is rotatable about, a polarized laser beam axis, and is configured to transmit and to reflect portions of the polarized laser beam. The attenuating optic provides predetermined attenuation of the polarized laser beam by changing the ratio between transmission and reflection of the polarized laser beam as a function of the incidence of the polarized laser beam on one or more partially reflective surfaces of the attenuating optic. The attenuating optic is rotatable about the polarized laser beam axis to control the incidence of the polarized laser beam on the one or more partially reflective surfaces of the attenuating optic, thereby to control the ratio between transmission and reflection of the polarized laser beam and provide a range of attenuation of the polarized laser beam.
