Title: Process and device for detecting foreign bodies in liquid
Inventor: OMETZ PIERR H M
IPC: G01N21/90
Filed: 1983-02-01
Granted: 1990-07-30
Abstract: In the device the image of the apparent surface of the liquid in rotation in the immobilised recipients is formed, by reflection, diffraction, refraction or attenuation of the light coming from a source, on a matrix of reception and read cells. In the matrix each cell is perfectly delimited and its position is identified by numerisation. A series of images is produced, of which a certain number are taken as reference and memorised. Each image is digitised and those images following the last memorised image is compared, cell by cell by a subtractor. The results of such a subtraction are compared with a threshold and results overstepping the threshold involve delivering a signal to a processor which controls a sort device arranged to eliminate undesirable units.
