摘要：

SPIFFI是一台AO馈电积分场摄谱仪，作为VLT上SINFONI的一部分运行，它将升级并在新的VLT仪器ERIS中作为SPIFFIER重新使用。2016年1月，我们利用新技术开发对SPIFFI仪器中的光学子系统进行了早期升级，以便正在进行的科学计划可以在2020年ERIS到来之前利用增强的性能。我们报告升级后的组件和SPIFFI的性能，包括吞吐量和空间和光谱分辨率的增益。我们展示了重新调试的结果，突出了科学计划使用升级后的SPIFFI功能的潜力。最后，我们讨论了额外的升级SPIFFIER将被实施之前，它被集成到ERIS。

英文摘要：

SPIFFI is an AO-fed integral field spectrograph operating as part of SINFONI on the VLT, which will be upgraded and reused as SPIFFIER in the new VLT instrument ERIS. In January 2016, we used new technology developments to perform an early upgrade to optical subsystems in the SPIFFI instrument so ongoing scientific programs can make use of enhanced performance before ERIS arrives in 2020. We report on the upgraded components and the performance of SPIFFI after the upgrade, including gains in throughput and spatial and spectral resolution. We show results from re-commissioning, highlighting the potential for scientific programs to use the capabilities of the upgraded SPIFFI. Finally, we discuss the additional upgrades for SPIFFIER which will be implemented before it is integrated into ERIS.
