Improvement of Imaging detectors of infrared, visible, and Ultraviolet Radiation.

天文学中的许多研究都需要在电磁光谱的蓝色和紫外区具有高灵敏度的电荷耦合器件。过去生产的蓝光敏感器件存在量子效率低、灵敏度变化、光学失真和严重干涉条纹等问题。这项获得SBIR第一阶段奖的研究将使用一种新型的电荷耦合器件，设计成在处理时具有最佳性能，以获得高蓝色灵敏度。将尝试两种不同的方法来减小电荷耦合器件的厚度，从而增加蓝色响应。此外，还将研究稳定电荷耦合器件灵敏度的方法。这项工作的目标是生产一种可应用于ccd的技术，从而在从近红外到软X射线的广泛光谱范围内产生高、稳定的灵敏度。这样的设备将用于天文学、医学和生物成像以及化学分析。

Charge coupled devices (CCDs) with high sensitivity in the blue and ultraviolet regions of the electromagnetic spectrum are required for many investigations in astronomy. Devices produced with blue sensitivity in the past have exhibited problems such as low quantum efficiency, sensitivity variations, optical distortion and severe interference fringes. The research undertaken with this SBIR Phase I award will use a novel CCD designed to have optimum performance when treated to obtain high blue sensitivity. Two different approaches will be tried to reduce the thickness of the CCD, thereby increasing the blue response. Methods of stabilizing the sensitivity of the CCD will also be investigated. The goal of this work is to produce a technology which can be applied to CCDs resulting in high, stable sensitivity across a wide spectral range from near infrared to soft x-rays. Such devices would be of use to astronomy, medical and biological imaging, and chemical analysis.
