Abstract: The present invention relates to an apparatus for measuring the three-dimensional (3D) shape of an object under water. The apparatus flashes a laser point (or a laser line) to an object under water and photographs the object through a CCD camera which is placed outside a water tank. The apparatus recognizes the laser point which is flashed to the actual object from the images photographed by the CCD camera, and then restores the 3D shape of the object by obtaining an actual absolute coordinate from an interaction formula between the pixel coordinate of the laser point and the actual absolute coordinate. Therefore, the apparatus can accurately measure a 3D shape such as a subject′s breast under water.

Abstract: In the conventional microwave imaging apparatus, the level of a matching liquid can change depending on the size of an object to be measured due to the variable size of the object, and the overflow of the matching liquid can occur through an open part in an exposure water tank during the operation of the microwave imaging apparatus because part of the top of the exposure water tank is open in order to position the object in the exposure water tank. In this context, the purpose of the present invention is to provide a microwave imaging apparatus which has an additional matching liquid supply tank capable of supplying a matching liquid to a microwave exposure water tank of a microwave imaging apparatus, and can regulate the level of a matching liquid through a pump or a pump controller capable of injecting or discharging a matching liquid into or from the microwave exposure water tank or the matching liquid supply tank. In particular, the provided microwave imaging apparatus can stop the operation of the pump when the matching liquid reaches a maximum allowable level by placing a liquid photo sensor at the maximum allowable level point of the matching liquid.

A clock management unit(113) provides a predetermined clock signal for an operation of the digital signal processor. A communication port(117) receives the control signal from a control host, and transmits the analysis result to the control host.
