An ultrasonic tester includes an ultrasonic sensor that applies ultrasound to a test object; a casing that holds the ultrasonic sensor immersed in a contact medium that allows the ultrasound to propagate therethrough, the casing including a test object-facing opening Further, there is circuitry configured to, when the test object-facing opening of the casing is passing an opening of the test object in a test direction of the test object, control a moving speed of the casing such that a region of contact between the test object and the contact medium entering the opening of the test object is kept within the opening of the test object.

A determination assist system including a first image generating section for generating a first planar image based on data of a first test index; a second image generating section for generating a second planar image based on data of a second test index; a differentiation section which differentiates the first planar image and the second planar image to generate a first differential image and a second differential image, respectively; a binarization section which binarizes the first differential image to generate a first binary image including a first region which is not less than a first threshold and a second region which is less than the first threshold, and binarizes the second differential image to generate a second binary image including a third region which is not less than a second threshold and a fourth region which is less than the second threshold; and a determination image generating section.

To improve the detection precision and detection efficiency and further to automatize the detection process, moisture in a honeycomb panel is detected as follows: the honeycomb panel is heated by a lamp; the surface temperature of the heated construction is measured by an infrared radiation thermometer; the measured temperature is displayed to roughly discriminate an abnormal portion (i.e., a portion containing moisture); the honeycomb panel is further heated continuously to detect temperature-change-rates at both abnormal and normal portions (i.e., a portion not containing moisture); and the two temperature-change-rates are compared with each other to discriminate a presence of moisture.
