三恩時棋盤分辨率測試卡幾何形狀畸變一致性

測試卡說明

YE06A測試卡被設(shè)計用來檢查幾何和分辨率組成部分。
數(shù)據(jù)
測試卡類似于一個由13×18的黑色和白色正方形區(qū)域以及由矩形區(qū)域在對應(yīng)于電子測試生成器14/19網(wǎng)格光柵線邊緣所包圍的棋盤。（整個圖卡發(fā)生器的水平網(wǎng)格線被劃分為相應(yīng)于42行）新的動力。
九個扇形星內(nèi)圓線條標(biāo)出625線結(jié)構(gòu)的過程中。較大的圓形線條標(biāo)出312線的結(jié)構(gòu)。橫向?qū)?yīng)的垂直線光柵分布著33個白格廣泛關註。它們對應(yīng)于2促進進步，3.5和5MHz頻率柵格。
應(yīng)用
•檢查幾何形狀和光柵的一致性優勢領先，如果有必要用電子生成網(wǎng)格的裝置迎來新的篇章。
•檢查信號生成的均勻性。
•檢查分辨率及其在圖像區(qū)域分布推動並實現。
•檢查后焦距薄弱點。

The YE06A test chart is designed for checking geometry and resolution.
DATA
Similar to a chessboard the test chart is composed of 13 x 18 black and white square fields which are surrounded by rectangular at the edges that correspond to the 14/19 grid raster lines of electronic test generators. (The division of the horizontal grid lines of these generators corresponds to 42 lines per complete picture.)
The inner circular lines of the nine sector stars mark a 625-line structure. The larger circular lines mark a structure of 312 lines. Horizontal resp. vertical line rasters are arranged in 33 white fields. They correspond to frequency raster of 2, 3.5 and 5 MHz.
UTILIZATION
•Checking geometry and the congruency of raster, by means of an electronically generated grid, if necessary
•Checking the uniformity of the signal generation.
•Checking resolution and its distribution over the picture area.
•Checking back focal distance.
