  • Publication number: 20100254715
    Abstract: A driving apparatus supplies a drive signal to an optical modulator corresponding to a phase modulation format, and also, divides a part of an output light from the optical modulator; extracts some optical component of the divided light, which is distant from a carrier frequency by integral multiple of a modulation frequency, to detect a power of the optical component; and feedback controls a duty ratio of the drive signal or a cross-point level thereof so that the detected power approaches a minimum value. Thus, it is possible to stably perform phase modulation with high precision.

  • Patent number: 7789532
    Abstract: A light source device includes a light source lamp, a rotary plate, a heat absorbing portion, and a filter mounting member. The light source lamp emits illumination light. The rotary plate includes multiple opening portions that are selectively disposed in the illumination light path of the light source lamp. A reflective filter that reflects light of a wavelength that acts a heat source in illumination light is provided in one of the multiple opening portions of the rotary plate. The heat absorbing portion absorbs heat included in reflected light reflected by the reflective filter in the opening portion. The filter mounting member disposes the reflective filter in the opening portion at a predetermined angle of inclination to the optical axis of the illumination light. By disposing the inclined reflective filter in the illumination light path, reflected light reflected by the reflective filter is reflected towards the heat absorbing portion.
