对于OCD刷扫成像的MTF,一般文章只给出了在与线阵垂直的刷扫情况下,线阵方向和垂直于线阵方向两个方向上的计算式.本文导出在与线阵交有任意角度的刷扫情况下,任意方向上的MTF计算式.OCD刷扫成像由OCD线阵的一维运动形成.对于这一成像方式的MTF的讨论,一般只考虑了沿线阵方向和垂直于线阵方向的MTF,并假定了刷扫方向与线阵方向垂直.下面给出一般情况下MTF的计算式及推导.
For OCD brush imaging MTF, the general article gives only the calculation of the direction of the line array and the direction perpendicular to the line array in the case of the vertical sweep with the line array. MTF calculation in any direction under any angle of brushing.OCD brushing imaging is formed by one-dimensional motion of OCD linear array.For the discussion of MTF in this imaging mode, only the direction along the linear array and perpendicular to MTF linear array direction, and assumed that the direction of brushing and linear array direction perpendicular to the following MTF under normal circumstances and derivation.
