目前正在为紫外线成像仪器开发自适应高速低噪声探测器电子设备，以便应用于天文学和行星科学空间飞行任务以及各种其他地面高速成像应用。欧空局JUICE 1和世界空间观测站2等即将进行的空间飞行任务要求紫外光子计数成像探测器具有高动态范围、高空间分辨率和高辐射容限。成像技术，可以适应不同的光度条件和优化图像空间分辨率对传入的光子事件率可以提供显着的性能优势。介绍了一种利用低噪声电容分割图像读出（C-CCD）3和自适应脉冲整形能力的光子计数微通道板（MCP）成像探测器。我们的实验设置提供了可控的光子计数率端到端的检测器性能测量和系统校准。它使用一个四通道快速数字化器，使我们能够轻松地研究各种数字脉冲整形技术和不同的整形时间常数，以评估其对检测器性能的影响。在本文中，我们描述了我们的实验室实验装置，说明了光子计数成像的方法，并描述了量化图像空间分辨率的技术。最后，我们提出了我们目前的一组结果比较测得的空间分辨率与理论确定从测量的固有电子噪声的系统。
Adaptive high speed low noise detector electronics are being developed for a UV imaging instrument for application to astronomy and planetary science space missions and for various other terrestrial high speed imaging applications. Forthcoming space missions such as ESA JUICE1and the World SpaceObservatory2have requirements for UV photon counting imaging detectors with high dynamic range, high spatial resolution and high radiation tolerance. Imaging techniques that can adapt to different luminosity conditions and optimise the image spatial resolution against the incoming photon event rate can provide significant performance advantages. We introduce an imaging photon counting Microchannel Plate (MCP) detector utilising a low noise Capacitive Division Image Readout (C-DIR)3with adaptive pulse shaping capability. Our experimental setup provides controllable photon count rates for end-to-end detector performance measurement and system calibration. It uses a four channel fast digitiser which enables us to easily investigate various digital pulse shaping techniques and vary shaping time constants to assess their impact on detector performance. In this paper we describe our laboratory experimental setup, illustrate the method of imaging from photon counting and describe techniques for quantifying the image spatial resolution. Finally we present our current set of results comparing the measured spatial resolution with the theoretical determined from the measured intrinsic electronic noise of the system.
