Title (EN) UNIFIED SCHLIEREN-INTERFERENCE APPARATUS,ESPECIALLY FOR ULTRACENTRIFUGES
(FR) DISPOSITIF UNIFIE A INTERFERENCE SCHLIEREN, NOTAMMENT POUR ULTRACENTRIFUGEUSES
Abstract: front page image
(EN)A unified schlieren-interference apparatus comprising along the optical axis a condenser lens, an element provided with a slit, a collimator, a cell, an optical projection system containing a cylindrical lens and a recording means. According to the invention, the element is placed in the focal plane of the collimator illuminating the cell and is provided with an equally spaced optical grid consisting of transparent and non-transparent strips and at least one slit perpendicular thereto. The element comprising the optical grid and at least one slit is placed in the apparatus so that both the schlieren recording and the interference recording appear on the same image simultaneously, without the necessity of any re-adjustment in the apparatus. The simultaneous appearance of both images are extremely adavantageous in the evaluation of both equilibrium and velocity measurements.
(FR)Dispositif unifie a interference Schlieren comprenant un objectif condensateur le long de l"axe optique, un element pourvu d"une rainure, un collimateur, une cellule, un systeme de projection optique contenant une lentille cylindrique et un moyen d"enregistrement. Selon l"invention, l"element est place sur le plan focal du collimateur eclairant la cellule et est pourvu d"une grille optique espacee de maniere reguliere se composant de bandes transparentes et non transparentes et d"au moins une fente perpendiculaire. L"element comprenant la grille optique et au moins une fente est place dans le dispositif de maniere que l"enregistrement Schlieren et l"enregistrement d"interference apparaissent sur la meme image simultanement, sans qu"aucun reajustement dans le dispositif ne soit necessaire. La presence simultanee des deux images est extremement avantageuse pour l"evaluation de mesures d"equilibre et de vitesse.
