在基特山顶,对一台包括64个PbS元件阵列的成象系统成功地进行了试验。在1.65微米对低对比度的太阳微粒初步拍摄了几张照片,其信噪比大于200,分辨率为1弧秒。本文讨论了对低对比度目标进行成象的红外系统的问题。 At the top of Kitt, a successful imaging system of 64 PbS arrays was successfully tested. At 1.65 microns, a few pictures were initially taken of low-contrast solar particles with a signal-to-noise ratio of more than 200 and a resolution of 1 arcsec. This article addresses the issue of infrared systems that image low-contrast targets.
