摘要： A voltage detector detects a voltage developing in a selected area of an object such as an integrated circuit by utilizing an electro-optic material equipped in an optical probe. A change in refractive index of the electro-optic material which is caused by the voltage in the object, is detected as a change of polarization of a light beam passing through the electro-optic material. In order to stably trigger a streak camera, the first reference light split before entering the electro-optic material and the second reference light split after emerging from the electro-optic material are used in the form of the difference in intensity between the two reference light beams for generating a trigger signal supplied to the streak camera.

摘要： A cylindrical lens (4) diverges a laser beam (L1) in the Y-axis direction (i.e., within the YZ plane) but neither diverges nor converges it in the X-axis direction (i.e., within the ZX plane). An objective lens (5) converges the laser beam (L1) emitted from the cylindrical lens (4) into a point P1 in the Y-axis direction and into a point P2 in the X-axis direction. A pair of knife edges (13) adjust the divergence angle (θ) of the laser beam (L1) incident on the objective lens (5) in the Y-axis direction. As a consequence, the cross section of the laser beam (L1) becomes an elongated form extending in the Y-axis direction at the point P2, while the maximum length in the Y-axis direction is regulated. Therefore, locating the point P2 on the front face of a work (S) can form an elongated working area extending in the Y-axis direction by a desirable length on the front face of the work (S).

摘要： An optical wavelength shifter shifts a wavelength of light over a wide range without need for using a large peak pump pulse. A nonlinear optical medium having a nonlinear refractive index is disposed interiorly of a laser resonator. A pump pulse and a light to be modulated are incident on a nonlinear optical medium to phase shift the light. With the provision of a timing delay unit, the timing at which the light to be modulated is incident on the nonlinear optical medium is delayed with respect to the timing at which the pump pulse is incident thereon.

摘要： The electrical signal observing device measures the electrical signal by applying the electrical signal to be measured to an optical amplifier in order to modulate a short pulse light train directed through the electrical amplifier. The electrical signal to be measured acts as a gain control for the optical amplifier. The photodetector detects the output of the optical amplifier and applies a resultant electrical signal to an integrator circuit after which the signal is displayed. The signal may be displayed in a time base fashion using a sweep generated by a delay system of the short pulse light train.

摘要： A voltage detector comprises a pulse light source, a delay means, a dispersing prism made of an electro-optic material and a linear image sensor. The electro-optic material senses a voltage developing in a selected area of an object as a change of its refractive index. An optical path of a pulse light is changed by the dispersing prism according to the change of its refractive index. An output pulse light emerging from the dispersing prism is detected by a linear image sensor. A waveform of the periodic voltage pulses can be detected by gradually delaying a phase of the pulse light emitted from the light source. The voltage developing in one-dimensional positions in the object can be also detected by employing a dispersing prism extending along the positions to be detected and a two-dimensional detector.
