摘要： A surface inspecting method including irradiating a laser light to a test object to generate an ultrasonic wave, irradiating a second laser light at a position apart by a known distance from a position where the laser light is irradiated and receiving a reflection light thereof, and correcting a generation surface wave of a received ultrasonic wave by using an ultrasonic wave other than the generation surface wave to thereby detect a flaw of the test object. A characterization of the generation surface wave is divided or integrated by the same characterization of the ultrasonic wave other than the generation surface wave included in an output signal to obtain a performance index value and obtain a depth of the flaw by applying the performance index value to a calibration curve in which a corresponding relation between the performance index value and the depth of the flaw is obtained preliminarily.

摘要： The variable gain amplifier includes a parallel connection of resistance R2 and capacitor C2. Resistance R2 may be replaced by inductance L, and bipolar transistors may be replaced by other types such MOS transistors. Resistance R2 gives a current feedback for transistor Q2, thereby lowering the mutual conductance “gm” of transistor Q2, and limiting the current flowing from voltage supply V0. The emitter area ratio (the emitter area of transistor Q2: the emitter area of Q3) made to be 1: n where “n” is greater than or equal to 1, thereby controlling each current. Capacitor C2 is connected in parallel with R2 connected with the base of transistor Q2 is a bypass capacitor for lowering the impedance of the base of transistor Q2 in higher frequency range. Capacitor C2 is a peaking capacitor, because it improves the high frequency characteristics.
