Изобретение относитс  к области телевидени , в частности к измерению параметров кииескоиов и отклон ющих систем дл  цветного телевидени .The invention relates to the field of television, in particular to the measurement of the parameters of kiyeskoi and deflecting systems for color television.

Известный способ определени  остаточного несведени  лучей иа экране кинескопа заключаетс  в том, что в катушки отклон ющей системы и системы сведени  подаютс  токи, обеспечивающие совмеп1ени  лучей на вертикальной н горизонтальной ос х растра. Остаточное несведепие лучей в диагональных област х экрана оцениваетс  визуально путем измерени  рассто ни  между п тнами люминофора , свет щимис  -под воздействием отдельных лучей (следов).A known method for determining the residual nonduction of the rays on the screen of a kinescope is that currents are provided in the coils of the deflecting system and the intelligence system, which provide for the combination of the rays on the vertical and horizontal axis of the raster. The residual non-absorption of the rays in the diagonal areas of the screen is estimated visually by measuring the distance between the spots of the phosphor that are illuminated by the individual rays (traces).

Такой способ оценки содержит значительную погрешность в св зи с необходимостью измерени  малых рассто ний (пор дка нескольких миллиметров) между свет щимис  п тнами люмииофора, имеющими размытие границы, что усугубл етс   влением наралакса . Кроме того, простое измерение рассто ни  между лучами не дает представлени  о характере остаточного несведени , так как ири этом не сообщаетс  информаци  об отклонении каждого из лучей от условного центра сведени .This method of evaluation contains a significant error due to the need to measure small distances (on the order of several millimeters) between luminiumophore luminous spots, which have a blurred border, which is aggravated by the appearance of naralax. In addition, a simple measurement of the distance between the rays does not give an idea of the nature of the residual ignorance, since this does not indicate the information about the deviation of each of the rays from the conventional center of knowledge.

Дл  определени  характера остаточного несведени  лучей на экране многолучевого кинескопа и повышени  точности измерени  вели-.To determine the nature of the residual non-convergence of the rays on the multipath kinescope screen and to improve the measurement accuracy.

чины остаточного несведени  но предлагаемому способу оценку остаточного несведени  лучей производ т по рассто нию следов лучей от условного центра сведени , что вводит информацию о характере остаточного несведени .The residual inconsistency values of the proposed method are based on the distance of the ray traces from the conditional center of information, which introduces information about the nature of residual inconsistency.

Считывание результатов производ т не методом оптического измерени  рассто ний между следами лучей, а измерением величины тока, необходимого дл  перемещени  каждого из лучей в условный центр сведени , что существенно повышает точность отсчета.The results are not read out by optical measurement of the distance between the traces of the rays, but by measuring the amount of current required to move each of the rays to the conventional center of knowledge, which significantly improves the accuracy of the reference.

Дл  перемещени  каждого из лучей в условный центр сведени  на магннтонроводахTo move each of the beams to a conventional intelligence center on magnet cables.

систем сведени  размещают дополнительные обмотки, в которые от источника посто нного напр жени  подаютс  регулируемые токи. По величине и знаку этих токов, которые могут быть пересчитаны в линейные величиныInformation systems place additional windings into which adjustable currents are supplied from a source of DC voltage. By magnitude and sign of these currents, which can be converted to linear values

остаточного несведени , можно судить о характере и величине остаточного несведени  в данной точке растра.residual failure, it is possible to judge the nature and magnitude of residual failure at a given raster point.
