Abstract: The present invention relates to a scanner having a flexible probe which is an apparatus capable of being utilized for an inspection on a weld zone of a general ferrite material and a stainless material and allowing an inspection to be performed on a fitting weld zone where it is difficult for a general phased array ultrasonic testing (PAUT) probe to approach.

Abstract: The present invention relates to a semi-automatic scanner for ultrasonic inspection of a branch pipe weld that has a small size and is able to perform an inspection while moving in a state of being attached to a test object by a magnetic force, thereby being applied to fittings having various shapes, such as a branch pipe and an elbow.

Abstract: Disclosed are a method for measuring the adhesive strength of a thin film using surface waves, and a computer-readable recording medium having a program for performing same recorded thereon. The method for measuring the adhesive strength of a thin film measures the adhesive strength between a substrate and a thin film by means of an electronic calculator, using sound waves measured from a thin film structure having a thin film formed on a substrate.

Abstract: A multiple beam path laser optical system using a multiple beam reflector. The multiple beam path laser optical system includes a light source part to generate a laser beam to be irradiated to a specimen, the multiple beam reflector to split a laser beam incident thereto from the light source part and to provide a plurality of optical paths, a main beam splitter to irradiate the laser beam split by the multiple beam reflector to the specimen, a transducer to excite the specimen for signal detection of the laser beam irradiated to the specimen, and a control part to analyze an interference pattern of a laser beam reflected from the specimen and recombined in the main beam splitter.
