Изобретение может быть использовано при исследовани х в отраженном свете углей (углепетрографи ), а также кристаллических веществ , например рудных минералов (минералографи ).The invention can be used in studies in the reflected light of coals (carbon-graphography), as well as crystalline substances, such as ore minerals (mineralography).
В минералогии и петрографии дл исследовани оптических свойств прозрачных минералов в проход щем свете щироко примен ют федоровский метод, при котором используетс универсальный федоровский столик, прикрепл емый к столику пол ризационного микроскопа.In mineralogy and petrography, the Fedorov method is widely used to study the optical properties of transparent minerals in transmitted light, using the universal Fedorov table attached to the table of a polarization microscope.
Однако федоровским методом исследуют оптические свойства анизотропных прозрачных веществ в проход щем свете; им нельз исследовать оптические свойства непрозрачных анизотропных веществ.However, the Fedorov method investigates the optical properties of anisotropic transparent substances in transmitted light; they cannot explore the optical properties of opaque anisotropic substances.
До насто щего времени оптические свойства непрозрачных веществ обычно исследовались в отраженном свете на плоских полированных щлифах (анщлифах), например угольных. Недостаткал1и этого способа вл ютс отсутствие объективного критери сохранени заданной ориентировки и необходимость изготовлени различно ориентированных полированных щлифов дл нахождени главных сечений оптической индикатрисы исследуемого вещества, например витринита, в образцах угл .Up to now, the optical properties of opaque substances have usually been studied in reflected light on flat polished slits, such as coal. The disadvantage of this method is the lack of objective criteria for maintaining a given orientation and the need to produce variously oriented polished slits to find the main sections of the optical indicatrix of the test substance, such as vitrinite, in coal samples.
Известен способ измерени отражательной способности некоторых анизотропных рудныхThere is a method of measuring the reflectivity of some anisotropic ore.
минералов на полированных поверхност х полущарий , которые вытачивают из монокристаллов способом, примен емым при изготовлении оптических линз; эти полущари исследуют на столике UTR-2.minerals on polished surfaces of the half-blades, which are machined from single crystals by the method used in the manufacture of optical lenses; these polushchary research on the little table UTR-2.
Существенным недостатком этого способа вл етс необходимость иметь чрезвычайно точно выточенные полущари , центр которых должен совпадать с центром вращающегос A significant disadvantage of this method is the need to have extremely precisely turned poluschary, the center of which must coincide with the center of the rotating
столика, так как только при этом условии сохран етс исходное нормальное падение света на полированную поверхность полущари при его поворотах в плоскости и пространстве. Изготовление полированных точных полущарий,table, since only under this condition the original normal incidence of light on the polished half-ball surface is maintained when it rotates in a plane and in space. The manufacture of polished precision polyshchary,
особенно из углей, - чрезвычайно сложна операци .especially from coal, the operation is extremely complicated.
Целью изобретени вл етс разработка сравнительно нростого, более точного и менее трудоемкого теодолитного способа псследоваип в отраженном свете оптических свойств углей.The aim of the invention is to develop a relatively simple, more accurate and less time-consuming theodolite method in reflection in the reflected light of the optical properties of the coal.
Указанна цель достигаетс тем, что изме )ение показателей отражени и угла между нормал ми к изотропным сечени м производ т в услови х падени света на полированный щлиф, имеющий форму щарового сегмента , который поворачивают в пространстве вокруг центра его кривизны в разных направлени х и по интенсивности отраженного светаThis goal is achieved by changing the reflection indices and the angle between the normals to the isotropic cross sections under the conditions of the incidence of light on the polished slit, which has the shape of a spherical segment, which is rotated in space around its center of curvature in different directions and along reflected light intensity
