The field of view characteristics of wide field birefringent (WFB) elements are compared with those of the Fabŕy-Perot (F.P.), Michelson (MI), and wide field Michelson (WFM) interferometers. Throughput gains of 50 to 300 or more with respect to the F.P. or MI are demonstrated. Further, it is shown that by proper choice of material WFB elements can have angular characteristics identical with WFM interferometers. The properties of misaligned and mismatched half-length WFB elements are calculated. It is shown that properly misadjusted WFB elements can exhibit throughput gains with respect to properly adjusted systems. Finally, a catalog of fringe patterns for WFB elements of different materials and differing angular misadjustment is presented.
将宽场双折射（WFB）元件的视场特性与法布里 - 珀罗（F.P.）、迈克尔逊（MI）和宽场迈克尔逊（WFM）干涉仪的视场特性进行了比较。结果表明，相对于F.P.或MI，其通量增益可达50至300或更高。此外，研究表明，通过适当选择材料，WFB元件可以具有与WFM干涉仪相同的角度特性。计算了未对准和不匹配的半长WFB元件的特性。结果表明，适当失调的WFB元件相对于适当调整的系统可以表现出通量增益。最后，给出了不同材料和不同角度失调的WFB元件的条纹图案目录。
