我们提出了新型光学和近红外（350 - 1650 nm）仪器的总体规格和科学目标，该仪器旨在大大扩大当前的外星智慧搜索（SETI）相空间。脉冲全天近红外光学 SETI (PANOSETI) 天文台将是一个专用 SETI 设施，旨在增加搜索天空区域、覆盖波长、观测到的恒星系统数量以及监测持续时间。该天文台将提供“全可观测天空”光学和宽视场近红外脉冲技术特征和天体物理瞬态搜索，能够测量整个北半球。最终实施的实验将搜索纳秒到秒时间尺度之间发生的瞬态脉冲信号。该光学组件将覆盖比当前 SETI 目标搜索大 250 万倍的立体角，同时还将每个光源的停留时间增加 10,000 倍。 PANOSETI 仪器将是有史以来第一个近红外广域 SETI 计划。快速响应光学和近红外探测器阵列（即多像素光子计数；MPPC）的快速技术进步使该计划现在变得可行。 PANOSETI 仪器设计采用创新的圆顶，内含 100 个菲涅尔透镜，可同时搜索超过 8,000 平方度的瞬态信号（参见 Maire 等人和 Cosens 等人的本次会议）。在本文中，我们描述了 PANOSETI 的总体仪器规格和科学目标。
We present overall specifications and science goals for a new optical and near-infrared (350 - 1650 nm) instru- ment designed to greatly enlarge the current Search for Extraterrestrial Intelligence (SETI) phase space. The Pulsed All-sky Near-infrared Optical SETI (PANOSETI) observatory will be a dedicated SETI facility that aims to increase sky area searched, wavelengths covered, number of stellar systems observed, and duration of time monitored. This observatory will offer an “all-observable-sky” optical and wide-field near-infrared pulsed tech- nosignature and astrophysical transient search that is capable of surveying the entire northern hemisphere. The final implemented experiment will search for transient pulsed signals occurring between nanosecond to second time scales. The optical component will cover a solid angle 2.5 million times larger than current SETI targeted searches, while also increasing dwell time per source by a factor of 10,000. The PANOSETI instrument will be the first near-infrared wide-field SETI program ever conducted. The rapid technological advance of fast-response optical and near-infrared detector arrays (i.e., Multi-Pixel Photon Counting; MPPC) make this program now feasible. The PANOSETI instrument design uses innovative domes that house 100 Fresnel lenses, which will search concurrently over 8,000 square degrees for transient signals (see Maire et al. and Cosens et al., this conference). In this paper, we describe the overall instrumental specifications and science objectives for PANOSETI.
