AI 中文总结
LUVCam是一款高性能低成本紫外/光学相机，采用商用CMOS传感器等技术，已在轨达TRL7，将用于QUVIK等空间天文任务，解决空间相机成本高、紫外传感器效率低的问题。
AI 中文摘要
长期以来，具备空间环境稳健性能与应用传承的天文级相机成本高昂，大幅限制了空间天文学的发展能力，形成了资源准入壁垒；此外，多数传感器在紫外波段的低量子效率，也导致紫外观测长期受限。LUVCam项目旨在解决上述两个问题，提供高性能、低成本的紫外/光学相机系统，足以支撑广泛的空间天文学任务。LUVCam采用大尺寸、低噪声、大像素、高量子效率的商用现货背照（前照）式CMOS传感器，搭配定制化读出电子学、固件及热机械结构，兼具卓越的科学能力与快时标下的精密传感器内导行，可实现稳定的高分辨率成像。LUVCam不受国际武器贸易条例（ITAR）限制且制造成本低廉，为空间望远镜的准入开辟了新机遇。本文介绍LUVCam，描述其性能特性及飞行技术演示的快速实现；LUVCam搭配定制小口径紫外望远镜，自2024年7月已在轨运行，达到技术 readiness 等级（TRL）7。LUVCam已列入多个近期轨道任务，包括2026年发射的第二颗技术演示立方体卫星，还将为QUVIK（双通道紫外瞬变天文学任务）提供焦平面相机。
英文摘要
Astronomy-grade cameras with robust performance and heritage in the space environment have long been costly, substantially limiting capacity for space-based astronomy and creating a resource barrier to access. Additionally, ultraviolet observations have historically been limited by the low quantum efficiency of most sensors in this wavelength range. The LUVCam program is designed to address both issues by providing a high-performance, low-cost, UV/optical camera system sufficiently capable to support a wide-array of space-based astronomy missions. LUVCam features a large format, low-noise, large pixel, and high quantum efficiency, commercial-off-the-shelf back(front)-side illuminated CMOS sensor, packaged with custom built readout electronics, firmware, and thermomechanical structure to provide both superlative science capability and precision on-sensor guidance at fast cadence to allow for stable high-resolution imaging. LUVCam is ITAR-free and cheap to fabricate, opening up new opportunities for access to space telescopes. Here we introduce LUVCam, describe its performance characteristics, and the rapid implementation of a technology demonstration for flight. LUVCam, coupled with a small aperture custom-built UV telescope, has been on orbit since July 2024 and has achieved Technology Readiness Level (TRL) 7. LUVCam is manifested for several more near-term orbital missions, including a second technology demonstration CubeSat for launch in 2026, and will provide both focal plane cameras for QUVIK, a two-channel UV transient astronomy mission.
