单光子灵敏和高时空分辨的大动态范围科学增强相机
Large Dynamic Range Science Intensified Camera with Single Photon Sensitivity and High Spatiotemporal Resolution
摘要
Abstract
An intensified camera contains a hybrid detector that combines two established technologies, MCP intensification and image sensing, which facilitates optimal configuration and is the preffered choice for each assembly unit to achieve photon counting imaging with single photon sensitivity and precise spatiotemporal resolution. Therefore, this equipment becomes an ideal large format image detector for science images, which need accurate position and temporal information under extremely low level light conditions. With a high speed gate power supply, this camera can provide not only an ultrafast exposure time, but also a very large operation range to extend operation in higher light level conditions. The configuration of the intensifier camera including the operation properties of its main components is described. The preferred combination and optimal assembly of each main component for a MCP intensifier is introduced, combining a power supply with ultrafast speed and high repetition frequency for photocathode gating, and an optical coupler with a megapixel image sensor for high speed readout. The science intensified camera can have a nanosecond and even sub-nanosecond temporal timing capability, and operates over a large dynamic range with two operation modes: analog mode and photon count mode. The camera is expected to operate in photon count mode with single photo detection sensitivity, a maximum counting rate more than 106 counts sec-1 cm-2, and a spatial resolution less than 10μm (FWHM).关键词
