Building Volumetric Appearance Models of Fabric Using Micro CT Imaging
This paper builds volume-appearance models based on density data from X-ray computed tomography (CT) scans and appearance data from photographs under uncontrolled illumination. The resulting models show extreme detail in closeups, while at larger scales the distinctive textures and highlights of a range of fabrics emerge automatically.

Pocket Reflectometry
A simple, fast solution for reflectance acquisition with a BRDF chart, a linear light source, and a video camera on a mobile phone. Convincing svBRDF results are obtained after less than 30 seconds of data capture in casual environments.

Microgeometry Capture Using an Elastomeric Sensor
This paper describes a system for measuring microscopic surface geometry using an elastomeric sensor and a single camera. The system is not affected by the optical characteristics of the surface and can be configured as a portable device. Results from a variety of real-world materials are presented.

CATRA: Interactive Measuring and Modeling of Cataracts
A novel interactive method to assess cataracts in the human eye by crafting an optical solution that measures the perceptual impact of forward scattering on the foveal region. The method goes beyond traditional evaluation procedures by computing maps for opacity, attenuation, contrast, and point-spread function of cataracts.
