High Spatial Resolution BRDFs with Metallic powders Using Wave Optics Analysis

This manuscript completes the analysis of our SIGGRAPH 2013 paper [Levin et al. 2013], ”Fabricating BRDFs at High Spatial Resolution Using Wave Optics” in which photolithography fabrication was used for manipulating reflectance effects. While photolithography allows for precise reflectance control, it is costly to fabricate. Here we explore an inexpensive alternative to micro-fabrication, in th...

Adaptive optics with pupil tracking for high resolution retinal imaging

Adaptive optics, when integrated into retinal imaging systems, compensates for rapidly changing ocular aberrations in real time and results in improved high resolution images that reveal the photoreceptor mosaic. Imaging the retina at high resolution has numerous potential medical applications, and yet for the development of commercial products that can be used in the clinic, the complexity and...

emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

Multishot for High Spatial Resolution

Conventional Cartesian non-diffusion pulse sequences acquire k-space in multiple excitations (a.k.a. shots). As the phase errors originating from motion during the diffusion preparation time are random in nature and large compared to the phase used to spatially encode the image, the use of multi-shot sequences with diffusion gradients is not straightforward, and in most cases severe image ghost...
