Multispectral detection and presentation of an object's characteristics
11523739 · 2022-12-13 · ·

An apparatus for capturing a multispectral image of an object is described. The apparatus includes one or more means for transmitting a beam of laser light at a first wavelength and a beam of laser light at one or more additional wavelengths different from the first wavelength. There is a means for causing the beams of laser light to travel in a coaxial path and a moving mirror. The beams of light bounce off the mirror thereby producing a two dimensional projection pattern. This pattern travels from the mirror along a first path to an object and wherein some of the laser light penetrates the object and travels to an internal structure of the object. The reflection of the laser light returns to a photo detector along a path different from said first path.

Systems and methods for performing gabor optical coherence tomographic angiography
11523736 · 2022-12-13 ·

Systems and methods are provided for performing optical coherence tomography angiography for the rapid generation of en face images. According to one example embodiment, differential interferograms obtained using a spectral domain or swept source optical coherence tomography system are convolved with a Gabor filter, where the Gabor filter is computed according to an estimated surface depth of the tissue surface. The Gabor-convolved differential interferogram is processed to produce an en face image, without requiring the performing of a fast Fourier transform and k-space resampling. In another example embodiment, two interferograms are separately convolved with a Gabor filter, and the amplitudes of the Gabor-convolved interferograms are subtracted to generate a differential Gabor-convolved interferogram amplitude frame, which is then further processed to generate an en face image in the absence of performing a fast Fourier transform and k-space resampling. The example OCTA methods disclosed herein are shown to achieve faster data processing speeds compared to conventional OCTA algorithms.
