  Explore uspto.gov May 23 2017 Patents
  
  A dual-modality apparatus for imaging of biological tissue includes a reflectance confocal microscopy (RCM) imaging apparatus and an optical coherence tomography (OCT) imaging apparatus. A first optical component reflects a first beam of light provided by a RCM imaging apparatus towards a sample and passes a second beam of light provided by an OCT imaging apparatus towards the sample, such that the first and second beam of lights share at least a portion of an imaging path.

4. Adaptive optics line scanning ophthalmoscope
  
  Explore uspto.gov Jun 19 2012 Ophthalmology , Patents
  
  A first optical module scans a portion of an eye with a line of light, descans reflected light from the scanned portion of the eye and confocally provides output light in a line focus configuration. A detection device detects the output light and images the portion of the eye. A second optical module detects an optical distortion and corrects the optical distortion in the line of light scanned on the portion of the eye.

  An apparatus for needle biopsy with real time tissue differentiation using one dimensional interferometric ranging imaging, comprising a biopsy device having a barrel and a needle, an optical fiber inserted in the needle, and a fiber optic imaging system connected to the optical fiber. The imaging system obtains images and compares the optical properties and patterns to a database of normalized tissue sample images to determine different tissue types. The physician performing the biopsy obtains feedback via a feedback unit associated with the biopsy device and which is connected to the imaging system. The feedback unit can provide visual, audible ...

7. Stabilized retinal imaging with adaptive optics
  
  Explore uspto.gov Jul 20 2010 Ophthalmology , Patents
  
  A system provides an optical image of an object. A first module tracks a reference feature of the object. A second module includes a source for an imaging beam, a scanning device to move the imaging beam along a portion of the object and a detection device receives a signal associated with an image of the portion of the object. The first module controls the position of the imaging beam relative to the reference feature to correct for the motion of the object. A third module detects a distortion of the object and compensates for the distortion.

9. Swept-source parallel OCT
  
  Explore SPIE Digital Library Feb 19 2009
  
  We present an optical coherence tomography (OCT) system that can create a full 2D cross-sectional image of a sample within one single spectral sweep of a swept source at a frame rate of 160 fps. The unique combination of line field and swept source technologies in a Fourier domain OCT configuration achieves ultrahigh imaging speeds with a greatly simplified wavelength swept source. The system was initially tested on reflective and diffuse targets.

  purpose. To describe the fine structure of the fovea in subjects with a history of mild retinopathy of prematurity (ROP) using adaptive optics–Fourier domain optical coherence tomography (AO-FDOCT). methods. High-speed, high-resolution AO-FDOCT videos were recorded in subjects with a history of ROP (n = 5; age range, 14–26 years) and in control subjects (n = 5; age range, 18–25 years). Custom software was used to extract foveal pit depth and volume from three-dimensional (3-D) retinal maps. The thickness of retinal layers as a function of retinal eccentricity was measured manually. The retinal vasculature in the parafoveal region was assessed ...
