Description

контрольной и испытуемой кассетах на снимках 9 и 10 наблюдаетс  неодинаковое смещение изображени  идентичных точек тест-объекга а, Ь, с, d н а , Ь, с , d по отношению изображени  координатног сетки 11 прикладной рамки кассеты.The test and test cassettes in pictures 9 and 10 show unequal displacement of the image of identical points of the test object a, b, c, d n a, b, c, d with respect to the image of the coordinate grid 11 of the applied frame of the cassette.

Эти смещени  вызывают продольный и поперечный параллаксы на стереопаре, образованной Сним.ками, полученными в контрольной п испытуемой кассетах.These displacements cause the longitudinal and transverse parallaxes on the stereo pair formed by the Snapshots obtained in the control and test cassettes.

Измерение параллаксов производитс  на стереоприборе, например стереокомпараторе .Parallax measurements are performed on a stereo device, such as a stereocomparator.

Оценку пригодности испытуемой кассеты дл  стереорентгенограмметрической съемки проводит по величине измеренных параллаксовAn evaluation of the suitability of the test cassette for stereopentmographic imaging is carried out by measuring the measured parallax
