However, conventional measurement fixtures and complex setups make it difficult to evaluate these minute deviations\u2014on the order of several micrometers and several arcseconds\u2014quickly and easily.<\/p>\n\n\n\n<p class=\"has-green-color has-text-color has-link-color has-medium-font-size wp-elements-014c0840d496b86729c1eb58a9e71089 wp-block-paragraph\"><strong>\u30fbSolutions<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By combining an HR-1100 for pitch and yaw with an SH-3100 for roll and vertical displacement, the entire change in stage orientation during motion can be visualized in real time and without contact.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Simultaneous four-axis measurement<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pitch, yaw, roll, and vertical displacement are measured simultaneously.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Real-time measurement<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system identifies when, where, and by how much the stage deviates during travel in real time.
