  7. Imaging system with low coherence light source

    Explore Article PatFT » Page 1 of 1 (Feb 23 2010) Patents

    Imaging system with low coherence light source An imaging system uses a low coherence light source to image objects at a relatively far distance (at least 10 cm) and/or of a relatively large size (having a dimension of at least 10 cm). An imaging plane is located such that its image path is substantially equal to a reference path that the light follows within the imaging device. The imaging plane has a thickness of about the coherence length of the light. Only light returning from the imaging plane forms part of the image. Light returning on other paths is effectively negated due to a lack of coherence. ...

    Contactless Method Of Measuring The Density Of A Porous Material, Using A Measurement Of The Refractive Index Of The Material Obtained By Optical Coherence Tomography (Wo 2010/015594) The contactless method of measuring the density of a porous material uses a measurement of the refractive index of the material obtained by optical coherence tomography. According to the invention, an optical coherence tomography technique is used to determine the optical path corresponding to the penetration through an object (20) made of the material by a light beam used in the technique; the thickness of the object is determined; the refractive index of the material is determined from the optical path and the thickness; and the density of the material is determined from the refractive index.

    Establishing Compatibility Between Two-And Three Dimensional Optical Coherence Tomography Scans (Wo 2010/017356) Advances in optical coherence tomography (OCT) have prompted a transition from time domain OCT, providing 2D OCT images, to spectral domain OCT, which has a 3D imaging capability. Yet conventional technology offers little toward the goal of inter-device compatibility between extant 2D OCT images and newer 3D OCT images for the same or comparable subjects, as in the context of ongoing monitoring the quantitative status of a patient's eyes. The inventive methodology is particularly useful to identify the scan location of tissue in a 2D OCT image within the 3D OCT volumetric data, thereby allowing clinicians to image a patient ...

    Colorimetric three-dimensional microscopy An optically reflective or translucent object (14) can be microscopically imaged in all three dimensions and in true color for observation by a human observer. An interferometric optical setup is employed, using the low temporal coherence of a tunable broad-band light source (10, 20) to resolve the axial dimension, a single opto-mechanical or electronic scanning mechanism for accessing different object depths, and a two-dimensional photo sensor device (15, 34) capable of demodulating the temporally or spatially modulated scanning signals to reconstruct the object's full volume. Three volume scans are carried out sequentially, and the tunable broad-band source (10, 20) is ...
