A monochromator including: a concave mirror which converts incident light into parallel light and emits the parallel light, a plane diffraction grating for diffracting the parallel light emitted from the concave mirror, first reflection means which reflects first light diffracted by the plane diffraction grating and causes the diffracted light to enter the plane diffraction grating as second incident light, second reflection means which reflects second diffracted light and causes the reflected light to enter the plane diffraction grating as third incident light, and an exit slit disposed in the vicinity of a focal point such that third diffracted light is reflected by the first reflection means, to thereby enter the plane diffraction grating as fourth incident light and such that fourth diffracted light is converged at the focal point by the concave mirror, to thereby enable extraction of light having a specific wavelength.

The present invention relates to a double pass monochromator that improves wavelength resolution and reduces the actual length thereof. A return reflection means 7 that reverses the direction of dispersion of the wavelength of the second pass light 1c, 1f emitted and incident on a diffraction grating 4 during the reflection. In addition, the angles of the incident and emitted light during separation of spectral components by the diffraction grating are identical during the first and second diffraction.

An optoacoustic modulator contains first and second optoacoustic media, to which first and second piezoelectric vibrators are attached respectively. Herein, both of the first and second optoacoustic media are designed in same measurements, wherein they are arranged in series along an optical axis of a light signal in such a way that crystal orientation of the first optoacoustic media differs from crystal orientation of the second optoacoustic media with an angle of inclination of 90.degree.. In addition, the first piezoelectric vibrator is attached to a first surface of the first optoacoustic media which is placed in parallel with the optical axis of the light signal, while the second piezoelectric vibrator is attached to a second surface of the second optoacoustic media which is placed in parallel with the optical axis of the light signal, wherein the first surface is directed perpendicular to the second surface. The light signal, corresponding to incoming light incident on the optoacoustic modulator, is input to the first optoacoustic media. Then, the light signal transmitted through the first optoacoustic media is input to the second optoacoustic media, from which a desired output corresponding to outgoing light is output. The first and second piezoelectric vibrators are controlled by modulation signals, which are independently adjusted to cancel polarization mode dispersions of the optoacoustic media. In addition, it is possible to improve ripple characteristic of loss-wavelength dependency characteristic of the optoacoustic media, while it is possible to reduce an amount of crosstalk that occurs at a high-speed modulation mode.

The present invention provides increased processing efficiency for service of performing predetermined processes on document data through cooperation among the processes over a network. If an error exists during document input in an input plug-in element before a start of rule-based processing, when documents are captured from the input plug-in element, contents of the error are stored in an error history memory, and documents normally inputted are subjected to processing of processing plug-in and output plug-in elements according to the rule. Also when an error occurs during the rule-based processing, the contents of the error are stored in the error history memory, and the rule-based processing is continued for normal documents. Error histories are referred to, and if an error exists, the error contents are reported on the basis of the error histories.

An optical spectrum analyzer 100 and a wavelength variable light source 101 have each a sweep synchronization start function. A correction function of the rotation speed of a motor 106 for varying the angle of a diffraction grating in a spectroscope 104 so that extracted wavelength and output signal light wavelength match over a setup sweep wavelength range is found from the output signal light wavelength characteristic relative to the rotation angle of a spectral element 119 and the extracted wavelength of the spectroscope 104, and the rotation angle of motor 106 for driving the spectroscope 104 is varied for each setup wavelength in accordance with the correction function, then sweep is performed.

摘要:
A photocoupler 3 splits the light from a low-coherence light source 1 into measuring light DL and local oscillator light KL. A photocoupler 5 receives measuring light DL arid is input to an optical circuit 7 to be measured. The photocoupler 5 splits the reflected light RL. A polarization controller 9 controls the state of polarization of the reflected light RL as split by the photocoupler 5. A photocoupler 13 allows local oscillator light KL to be incident on a reflector mirror 16 and splits local oscillator light KL. A photocoupler 11 combines the reflected light RL as controlled in the state of polarization by the polarization controller 9, with the local oscillator light KL.
