摘要： A method for producing a multilayer tissue phantom involves successively forming at least two layers, each layer formed by depositing a viscous flowable material over a supporting element or over a previously formed layer of the phantom supported by the supporting element, selectively redistributing the material while material is solidifying to control a thickness distribution of the layer, and allowing the material to solidify sufficiently to apply a next layer. The supporting element supports the material in 2 or 3 directions and effectively molds a lumen of the tissue. The neighboring layers are of different composition and of chosen thickness to provide desired optical properties and mechanical properties of the phantom. The phantom may have selected attenuation and backscattering properties to mimic tissues for optical coherence tomography imaging.

摘要： A scanning optical delay line includes an optical path element that rotates about its central axis, such that a face is intermittently incident a beam of light to be optically delayed. When the beam is not incident the face, it is reflected onto a reinsertion line which provides a second opportunity for the beam to intersect the optical path element. The optical path element may include one or more parallelogram prisms, or parallel reflective surfaces to provide a substantially linear optical path length variation during the scan, which is produced by the rotation of the optical path element. A highly linear part of the rotation can be maximally used providing a high duty cycle, high linearity scanning optical delay line that permits high quality, high data rate applications.
