1. A method of ultrasonic non-destructive testing an object, comprising the steps of:
moving a phased array ultrasonic transducer relative to the object in a first direction;
repeatedly transmitting a steered coherent wave towards the object using said transducer;
receiving signals reflected from the object using said transducer and storing the received signals in memory;
beamforming diffuse components of the received signals to determine pixel values for a surface of the object; and
creating a texture map of the object based on said pixel values.
