Double VPH Tunable Filter

AST-0352991/泰勒，加州该奖项将支持开发一种基于两个连续体积相位全息光栅的新型天文可调滤光片。将进行广泛的模拟，并将建立一个桌面原型。如果成功，这种滤光器可能会比类似带宽的滤光器具有更高的效率，并改善各种天体物理目标的成像能力。这项工作可能会为建造类似的大望远镜仪器提供重要的见解。

AST-0352991/Taylor, CaltechThe award will support the development of a novel tunable filter for astronomy based on two sequential Volume Phase Holographic gratings. Extensive simulations will be performed and a tabletop prototype will be built. If successful, such filters may allow higher efficiency compared to filters of similar bandwidths, and improve imaging capabilities of a variety of targets of astrophysical interest. This work may provide important insights in the construction of similar instruments for large telescopes.
