摘要： Apparatus and methods are described for performing structure measurement on a tear film of an eye of a subject. At least a portion of a surface of the tear film is illuminated using a broadband light source. A spectrum of light of the broadband light that is reflected from at least one point of the tear film is measured, using a spectrometer. Color information for a plurality of points of the tear film is obtained, by imaging a field of view of the tear film using a color camera. Using a processing unit, data from the color camera and data from the spectrometer that are indicative of characteristics of the tear film are received, and based upon a combination of the data received from the color camera and the data received from the spectrometer, an output is generated that is indicative of a structure of the tear film.

摘要： An OCT imaging system (100) comprising a radiation emitter (SLD), a radiation receiver CCD), an interferometer (FC, PC, X-Scan, Y-Scan), a controller (COMP) which controls the emitter and processes received radiation data according to OCT to provide an output image. The controller (COMP) forms a spectrum of spatial frequencies along the depth direction. It calculates from the spectrum local spectra of spatial frequencies or periods along the depth direction for individual volume elements along the depth direction. It translates the local spectra of spatial frequencies or periods along the depth direction into the OCT image domain. It maps the local spectra into the volume elements to provide sensitivity on the nano-scale whereas the volume elements are in the micro-scale. The controller calculates information parameters from the translated and mapped local spectra. Thus the system (100) achieves nano-scale sensitivity although the volume elements are at the micro-scale.

摘要： Systems and methods for generating 3D representations of shape and color texture of a test surface are described. In one aspect, surface topography interferometers are equipped with a multi-element detector and an illumination system to produce a true-color image of the measured object surface. Color information can be presented as a true-color two-dimensional image or combined with topography information to form a three-dimensional representation of the shape and color texture of the object, effectively creating for a human observer the impression of looking at the actual part.

摘要： Fourier domain a/LCI (faLCI) method which enables in vivo data acquisition at rapid rates using a single scan. Angle-resolved and depth-resolved spectra information is obtained with one scan. The reference arm can remain fixed with respect to the sample due to only one scan required. A reference signal and a reflected sample signal are cross-correlated and dispersed at a multitude of reflected angles off of the sample, thereby representing reflections from a multitude of points on the sample at the same time in parallel. Information about all depths of the sample at each of the multitude of different points on the sample can be obtained with one scan on the order of approximately 40 milliseconds. From the spatial, cross-correlated reference signal, structural (size) information can also be obtained using techniques that allow size information of scatterers to be obtained from angle-resolved data.
摘要翻译：傅立叶域a / LCI（faLCI）方法，其能够使用单次扫描以快速的速率进行体内数据采集。通过一次扫描获得角度分辨和深度分辨的光谱信息。由于仅需要一次扫描，参考臂可以相对于样品保持固定。参考信号和反射样本信号以相对于样本的多个反射角度相互相关并分散，从而表示来自样本上多个点并行同时的反射。可以通过大约40毫秒数量级的一次扫描获得关于样本上多个不同点的每个样本的所有深度的信息。从空间相互关联的参考信号，也可以使用允许从角度分辨数据获得散射体的尺寸信息的技术来获得结构（尺寸）信息。
