The Large Synoptic Survey Telescope (LSST) camera will be made as a mosaic assembled of 189 large format Charge Coupled Devices (CCD). They are n-channel, 100 micron thick devices operated in the over depleted regime. There are 16 segments, 1 million pixels each, that are read out through separate...

2022年11月21日 · 时空遗珍巡天（Legacy Survey of Time and Space, LSST）是西蒙尼巡天望远镜（Simonyi Survey Telescope）将要执行的为期十年的巡天项目。 西蒙尼巡天望远镜是目前正在建设中的广视野巡天望远镜，预计2023年左右建成初光。 这架望远镜坐落在智利北部科金博大区帕穹山的伊尔佩恩峰的薇拉·鲁宾天文台（Vera C. Rubin Observatory, VRO），海拔2682米，与双子望远镜（Gemini Telescope）和南方天体物理研究望远镜（SOAR）相邻。 薇拉·鲁宾天文 …

LSST’s dedicated survey instrument will be a 189-chip mosaic of fully-depleted n-channel CCDs with compact, low power readout electronics. Prototype 16Mpixel sensors demonstrating low noise, fast readout, excellent image quality, tight mechanical tolerance, and good reproducibility have been received from two producers.

LSST的科学目标主要包含： 观测 弱重力透镜 以探测物质和能量； 寻找太阳系中的小天体，尤其是近地小行星和古柏带天体； 侦测 瞬变光学现象，例如新星和超新星； 绘制银河系地图。 LSST原计划2014年就要出光并投入使用，但貌似也是资金出了问题，目前进度 ...

With 3.2 gigapixels built into supersensitive CCDs aimed at the night sky, very little can escape the vision of the LSST camera. The key to achieving the wide range and massive images that make LSST so unique is modularity, which guides the design and assembly process.

2021年8月13日 · LSST采用独特的三透镜光学组件和世界上最大的CCD相机。 望远镜的运动由磁力马达驱动，确保从一个观测场到另一个观测场的快速、平稳和安静的旋转。

2007年12月1日 · In this initial phase of CCD development, we have targeted specific technology challenges at competitively selected vendors, with the goal of establishing both the technical characteristics of...

This thesis will present the design, implementation, and testing of a high voltage Charge-Coupled Device (CCD) controller ASIC for the Large Synoptic Survey Telescope (LSST), which will be used to study dark energy and dark matter.

The charge-coupled device (CCD) sensors that make up the LSST Camera's focal plane are mounted on 21 platforms called rafts, with each raft comprising a 3x3 square of sensors, for a total of 189 CCDs.

2025年3月14日 · The LSST Camera is the largest digital camera ever built. Its 3,200-megapixel image sensor comprises 189 high-resolution CCD image sensors arranged across 21 separate rafts of nine sensors each.
