儀科中心開發以單軸複數刀口演算法進行鏡頭品質量測方法，係利用準直儀產生光源，將光源照射至特殊光學組件。移動單軸馬達對待測鏡頭進行對焦量測，經由感測器取像得到成像於軸上及離軸之數個刀口測試圖案。並讀取成像圖案資料傳給電腦，利用數位影像處理方式，將成像圖案由刀口演算法處理，求出物理上的光學調制轉換函數量測值。

A tilted edge algorithm was used to develop a measuring machine for imaging lens characteristics. We used an infinite conjugate setup and folding of collimating beam design. The device measured an imaging optics in several different field angles simultaneously. This measurement can be performed in a single snapshot, which is often less than one second. The dimension of this measurement setup up to be as small as a desktop instrument.
