摘要： Method and apparatus for measuring the waviness of an aerodynamic surface includes a sensing unit that provides a plurality of data values which indicate the vertical deflection of a sensor at predetermined positions along the surface. A microprocessor receives the plurality of data values and processes the values in accordance with a method to determine the waviness of the surface. The microprocessor determines which of the plurality of data points have a convex curvature with respect to the data points to which it is adjacent and uses the convex data points to define lines which are tangent to the surface. The tangent lines are used to identify waves in the surface. The depth and length of each wave is determined from the tangent lines and the waviness calculation performed in accordance with a predetermined waviness formula.

摘要： An improved ultrasonic inspection system is provided which allows ultrasonic inspection to be performed using either of two ultrasonic frequencies and which also provides improved system sensitivity and dynamic range. In operation, the system produces two signals, one an amplified receive transducer signal and the other an attenuated receive transducer signal. Each signal is converted into a logarithmic representation. The two logarithmic representations are selectively provided to a read-only memory, which operates to output a signal corresponding to the receive transducer signal. Means are also provided which allows the system to use either of two ultrasonic frequencies.
