Fast wavefront sensing with new APD detector arrays

近年来，全世界对空间态势感知概念的关注已经走到了前列，涵盖了从小行星等近地物体到人造轨道碎片，再到监测宝贵空间资产安全的**领域。加拿大在担任多年的积极观察员之后，**最近成为机构间空间碎片委员会的正式成员。加拿大最近还与澳大利亚、英国和美国签署了《空间态势感知协议》。这将使**能够协调使用每个伙伴的空间能力，以识别和理解空间物体。**共享资源可以通过补充**覆盖范围提供持续的监控、身份验证和验证，特别是在危急情况下。**霍尼韦尔已经发现了一个机会，通过将新的探测技术**集成到他们的相机中，特别是使用Dalhousie的查普曼团队擅长的APD阵列。**两项新兴技术一直是霍尼韦尔航空航天国际系统**部门的重点，但它们没有能力追求非常有前途的第三项技术--APD阵列。**我们建议Engage计划与霍尼韦尔航空航天公司合作，共同追求领先的**技术来解决这些问题。将我们自己在天文学领域的增值应用作为这项研究的额外**动力。**为了便于详细了解这些应用的领先技术(**雪崩光电二极管探测器阵列--APD)，我们将分析和表征这些设备，向霍尼韦尔航空航天公司提供所需的**探测器参数，以便他们能够评估这项技术的可行性。

The worldwide focus on the concept of Space Situational Awareness (SSA) has come to the forefront in recent**years, encompassing everything from near Earth objects (NEO) such as asteroids to man-made orbital debris, to**the area of monitoring the security of valuable space assets. After being an active observer for some years,**Canada recently became a full member of the Inter-Agency Space Debris committee. Canada has also recently**signed, along with Australia, the U.K., and the USA, the Space Situational Awareness Accord. This will allow**for coordinated use of each partner's space capabilities for identifying and understanding objects in space. The**shared resources could provide continuous monitoring and authentication and validation via complementary**coverage especially for critical situations.**Honeywell has identified an opportunity to expand their company by integrating new detection technologies**into their cameras, and specifically using the APD arrays which Chapman's group at Dalhousie has expertise in.**Two emerging technologies have been a focus of the HONEYWELL AEROSPACE International Systems**division, but they do not have the capability to pursue a very promising third technology, APD arrays.**We propose to the Engage program to work with Honeywell Aerospace over the our joint pursuit of leading**technologies to address these issues, with our own value added applications in astronomy as an additional**motivator to this research.**To facilitate a detailed understanding of a leading technology for these applications (detector arrays of**Avalanche Photo-Diodes -- APDs), we will analyze and characterize these devices, providing the needed**parameters on the detectors to Honeywell Aerospace such that they can assess the viability of this technology.
