摘要：
Diffraction causes light to bend toward and perpendicular to an object's edge. In a current peep's aperture, diffracted light is neither controlled nor eliminated. In current peeps, diffracted light impairs accuracy, therefore current apertures must be oversized to allow space for the diffracted light. Visual size and shape of current aperture will vary with changes in light diffraction. Slotted peep (22) eliminates detrimental effects of diffracted light from its aperture. By surrounding an open space with the open ends of slots, a space is defined that has virtually no physical edges. Slotted peep (22) confines diffracted light within the slot. The figure shows slotted peep (22), however a user looking through slotted peed (22) sees (20). Light diffracted perpendicular to the edges of the slots darkens the slots. Slotted peep's aperture (20) will be virtually free of diffracted light and will not have the aforementioned shortcomings of current peeps.
摘要（中）：
衍射导致光朝向和垂直于物体的边缘弯曲。 在目前的窥视孔径中，衍射光既不受控制也不消除。 在目前的窥视中，衍射光会损害精度，因此电流孔径必须过大，以便衍射光线的空间。 电流孔径的视觉尺寸和形状将随着光衍射的变化而变化。 开槽窥视（22）消除衍射光从其孔径的有害影响。 通过围绕具有开口端的开放空间，定义了几乎没有物理边缘的空间。 开槽的窥视（22）将衍射光限制在槽内。 该图示出了开槽窥视（22），然而，通过开槽纹（22）看的用户看到（20）。 垂直于插槽边缘衍射的光使插槽变暗。 开孔的孔径（20）将几乎没有衍射光，并且不会有上述当前窥视的缺点。
