Illumination/Display Technologies in Vision Research

描述(由申请人提供)：这是一项基于最新可用技术的建议，允许简单地实施过去已知但困难的心理物理和成像程序。新的超亮LED(发光二极管)现在使呈现没有激光斑点的高亮度显示器成为可能。基于液晶或MEMS镜面的空间光调制器(SLM)使这些显示器具有必要的高对比度。由此产生的显示使马克斯韦尔式的心理物理学在非常高的速度、更大的强度范围和高线性度下成为可能。同样的技术，应用于眼前部组件(晶状体、角膜、玻璃体)的实时成像，将允许在没有激光的情况下使用共焦技术进行成像。最后，有了新的可访问的波长，我们可以定制成像，以提供真正在近红外中的伪彩色图像，但这可能与熟悉的可见光彩色图像直接相关。因此，这项提案涉及眼科研究的三个明显截然不同的领域，这些领域通过使它们成为可能的技术联系在一起。

DESCRIPTION (provided by applicant): This is a proposal based in newly available technologies to allow simple implementations of psychophysical and imaging procedures that have been known but difficult in the past. New ultra-bright LEDs (light-emitting diodes) now make it possible to present high brightness displays without laser speckle. Spatial light modulators (SLMs), either liquid crystal or MEMs mirror based, allow these displays to have the necessary high contrast. The resulting displays make possible Maxwellian view psychophysics at very high speeds, extended intensity range and high linearity. The same technologies, applied to live imaging of the anterior ocular components (lens, cornea, vitreous) will allow imaging using confocal techniques without lasers. Finally, with the newly accessible wavelengths, we can tailor the imaging to give a pseudo-color image that is really in the near infrared, but that can be directly related to the familiar visible colored images. This proposal therefore addresses three apparently quite different areas of ophthalmic investigation, linked by the technologies that will enable them.
