Portable device for the contactless measurement of objects

A portable measuring device for contactless measurement of a diameter of an elongated object, comprising:

• a light beam generator that generates a light beam and emits the light beam in a first direction;
• a first light beam deflector element disposed frontally with respect to the light beam generator, the first light beam deflector receiving the light beam generated by the light beam generator and deflecting the light beam along a beam path;
• a measuring region disposed along the beam path, the first light beam deflector element being disposed at one side of the measuring region;
• a second light beam deflector element disposed at a second side of the measuring region opposite the first deflector element, the second light beam deflector receiving the light beam deflected by the first light beam deflector element, and the second light beam deflector element deflecting the received light beam in a second direction opposite the first direction;
• a lens configured to receive the deflected light beam from the second light beam deflector element and create a light beam with a real image of the elongated object;
• a light beam splitting device located to receive the light beam of the real image from the lens and configured to split the light beam of the real image into two parts, each part forming a respective image of the elongated object, and each part being directed along an image path;
• a first linear image sensor disposed along one of the image paths and a second linear image sensor disposed along the other one of the image paths, the first linear image sensor provided with sensitive elements disposed linearly along a first plane and the second linear image sensor provided with sensitive elements disposed linearly along a second plane different from the first plane, the first and second planes of the first and second linear image sensors define respective axes different from each other, the first and second linear image sensors measure quantity of light along the axes, each of the first and second linear image sensors being configured to detect quantity of light impinging thereon and to convert detected light into electrical quantities;
• a first electronic image acquisition circuit connected to the first linear image sensor and a second electronic image acquisition circuit connected to the second linear image sensor;
• the first and second electronic image acquisition circuits each being configured to detect the electrical quantities of the respective first and second linear image sensors and to convert the detected electrical quantities into a sequence of numerical values;
• and
• an electronic image processing component connected to the first and second electronic image acquisition circuits and receiving the numerical values therefrom, the electronic image processing component is configured to use the numerical values to determine the diameter of the elongated object.
