摘要： An optical fiber probe which has a minute opening on the top of a sharpened tip is allowed to get close to a sample, and the probe is moved by a piezo actuator along x- and y-axis directions so that a minute spot beam emanating from the minute opening can scan over the sample. For circular polarization modulation to be incorporated in the process, a beam, before it is incident on the optical fiber probe, is given an optical delay changing at a frequency of p (Hz) by means of a piezo-optical modulator. A minute spot beam emanating from the minute opening passes through the sample to be received after the passage through an analyzer by a light receiving element. The output from the light receiving element is fed to a lock-in amplifier, p- and 2p-components are separated through lock-in rectification, and they are rendered images by a controller.

摘要： A sound field switcher inputs an output sound field signal from a sound field producer. The inputted sound field signal is delayed sequentially by plural delayers, after which they are multiplied by coefficients by plural multipliers, and the multiplied results are all added by an adder. Coefficients stored in an area of a memory indicated by a coefficient counter are read out and set to the plural multipliers. The sound field switcher carries out control of the timing for switching the sound field signal produced by the sound field producer and the timing for the coefficient counter to commence counting. Assuming the time required for switching the sound field to be N sampling periods, in case of carrying out a sound field switching from a sound field A to a sound field B, a sound field switching controller issues an order to the coefficient counter so as to count up one by one from 0 to N, and on each count the coefficients stored in an area of the coefficient memory is set to the multipliers. When the count value of the coefficient counter comes to (N/2) or nearest to (N/2), the sound field switching controller issues an order to the sound field producer to output the sound field signal of the sound field B. When the count value of the coefficient counter comes to N, the switching from the sound field A to the sound field B is completed.
