Apparatus to detect and measure contents of miniature vessels

摘要

An apparatus to determine the volume of fluids in batteries (3) of vessels forms a two-dimensional structured image, with a unidimensional camera (1), and a structure (4) which moves in relation to it in the camera view and out of its view behind the battery (3) of vessels. Continuous timed scanning by the camera gives a two-dimensional image of the moving battery (3) and structure (4), to be processed by an evaluation unit (2) to determine the fluid vols. The structure (4) is attached to the battery (3) so that, when the battery (3) is moved in the field of view of the camera (1), it is also moved synchronously or asynchronously. The structure (4) can be a rotating cylinder, in a fixed position behind the battery (3) of vessels and out of the camera (1) view. Its rotation round its axis moves the structure (4) in relation to the camera (1). The structure (4) on the cylinder is illuminated at an angle with simultaneous partial screening by a shadow unit for a clear view by the camera (1) and light passes through the moving battery (3) of vessels over the cylinder. The cylinder is of a translucent material.
