Sofradir 参与制造探测器，这些探测器覆盖了从短波红外到超长波红外的红外域中的大范围波长，适用于不同类型的应用。因此，需要不同类型的 ROIC 架构来覆盖这些不同类型的应用和操作条件。作为红外市场的主要参与者，Sofradir 开发了众多 ROIC，其架构能够满足战术、商业和太空领域的大多数红外应用。 Sofradir 现在能够推出一款新型探测器（384x288，间距为 15 μm），专为 SWIR 领域中的极低通量应用（例如天文学）而设计。这种新的 ROIC 是在 CNES 支持下开发的，包括一个 SFD（每个探测器的源跟随器）输入级，能够实现高增益、低读出噪声和极低功耗。在本文中，我们将描述这种新型探测器的架构和功能。然后，将描述电光特性和结果。最后介绍了该类探测器的主要应用。
Sofradir is involved in the manufacturing of detectors which cover a large range of wavelengths in the infrared domain from SWIR up to VLWIR for different kind of applications. Thus, different types of ROIC architectures are needed to cover these various kind of applications and operating conditions. As a major player of the infrared market, Sofradir has developed numerous ROIC with architectures enabling to answer most of the infrared applications in tactical, commercial and space domains. Sofradir is now able to present a new detector (384x288 with a 15 μm pitch) especially designed for very low flux applications in the SWIR domain (as astronomy for example). This new ROIC has been developed with CNES support and includes a SFD (Source Follower per Detectors) input stage enabling to achieve a high gain as well as a low readout noise and a vey low power consumption. In this paper, we will describe the architecture and functionalities of this new detector. Then, electro-optical characterizations and results will be described. Finally, main applications of this kind of detectors will be presented.
