This project aims to deploy a cryogenic camera system to improve the outputs of astronomical telescopes. The system is equipped with an emerging detector technology, a near-infrared Avalanche Photo-Diode array, capable of high cadence imaging with frame rates of 10 - 1,000 Hz at a wavelength of around 2.2 microns. This new technology is a key component to the future of adaptive optics systems for astronomical telescopes as it allows the rapid measurements necessary to correct the image blurring introduced by the Earth's atmosphere. No expertise currently exists in Australia with this new technology. Capitalising on previous investment, the camera system is intended to fill a capability gap in local expertise and to ensure the potential of the next generation of telescopes is realised and strengthen our competitive edge for frontier instrumentation across the wider Australian imaging community.

该项目旨在部署低温摄像系统以提高天文望远镜的输出。该系统配备了一种新兴的探测器技术，即近红外雪崩光电二极管阵列，能够在波长约为 2.2 微米的情况下以 10 - 1,000 Hz 的帧速率进行高节奏成像。这项新技术是天文望远镜自适应光学系统未来的关键组成部分，因为它可以进行必要的快速测量，以纠正地球大气层造成的图像模糊。目前澳大利亚尚不具备这项新技术的专业知识。该相机系统利用之前的投资，旨在填补当地专业知识的能力差距，确保实现下一代望远镜的潜力，并增强我们在更广泛的澳大利亚成像界的前沿仪器的竞争优势。
