摘要： Systems configured to generate output corresponding to defects on a specimen and systems configured to generate phase information about defects on a specimen are provided. One system includes an optical subsystem that is configured to create interference between a test beam and a reference beam. The test beam and the reference beam are reflected from the specimen. The system also includes a detector that is configured to generate output representative of the interference between the test and reference beams. The interference increases contrast between the output corresponding to the defects and output corresponding to non-defective portions of the specimen.

摘要： An optical fiber scanner is used for multiphoton excitation imaging, optical coherence tomography, or for confocal imaging in which transverse scans are carried out at a plurality of successively different depths within tissue. The optical fiber scanner is implemented as a scanning endoscope using a cantilevered optical fiber that is driven into resonance or near resonance by an actuator. The actuator is energized with drive signals that cause the optical fiber to scan in a desired pattern at successively different depths as the depth of the focal point is changed. Various techniques can be employed for depth focus tracking at a rate that is much slower than the transverse scanning carried out by the vibrating optical fiber. The optical fiber scanner can be used for confocal imaging, multiphoton fluorescence imaging, nonlinear harmonic generation imaging, or in an OCT system that includes a phase or frequency modulator and delay line.

摘要： Mechanically robust minimal form factor OCT probes suitable for medical applications such as needle biopsy, intraluminal and intravascular imaging are achieved in part by employing compound lenses with some or all of the optical elements, including an optical fiber, to be thermally fused in tandem. To achieve a desired working distance without increasing a diameter of the optics assembly, a spacer can be disposed between the optical fiber and focusing optics. The compound lens configuration can achieve higher transverse resolution compared to a single lens at a desired working distance without increasing the probe diameter. In exemplary needle biopsy embodiments, the optical assembly is encapsulated in a glass housing or metal-like housing with a glass window, which is then selectively passed through a hollow needle. Esophageal imaging embodiments are combined with a balloon catheter. Circumferential and three-dimensional spiral scanning can be achieved in each embodiment.
