    摘要: This method is based on the radiation-matter interaction in a structure having discontinuities and where electron transport occurs in at least one layer. To this end, a stimulation signal is sent through the device under test and simultaneously at least one source of radiation sends incident radiation towards the surface of the device. The secondary radiation emitted by the device is detected together with the response of the device. The signals are compared, either individually or in combination, with a reference.

    摘要: An apparatus and method for determining the volume, form and weight of fish or other objects is presented. A linescan camera records a top view of an object and at the same time records a profile view of the object reflected by a mirror located adjacent to the object. The mirror is positioned to reflect a view of the object which is perpendicular to the direct view of the camera and to the direction of motion of a conveyor belt along which the object moves. As the object moves along a conveyor belt through the field of view of the camera, a number of cross-sectional images are recorded and transmitted to a microprocessor. The microprocessor determines the maximum width of each cross-section from the direct image and the maximum thickness from each cross-section reflected image. Based upon the width and height of each cross-section and a form factor and estimated object density, the microprocessor calculates volume ane weight for each cross-section and adds the series of object cross-sections together to determine a volume and weight of the object.
