Diffractive Catheter Enhances OCT Imaging

Facebook X LinkedIn Email
A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption. Called a diffractive catheter, the device was developed by researchers from Johns Hopkins University and the University of Washington. Currently, such catheters and endoscopes are designed to work at around 1300 nm, but a smaller wavelength is more convenient in achieving an ultrahigh-axial resolution with a broadband light source. Reflected spectra of the...Read full article

    chromatic aberration
    Chromatic aberration is an optical phenomenon that occurs when different wavelengths (colors) of light are refracted by a lens or optical system, leading to a failure to focus all colors to the same convergence point. This results in colored fringes or halos around the edges of objects, reducing the overall image quality and sharpness. Key points about chromatic aberration include: Cause: Chromatic aberration arises because different colors of light have different refractive indices when...
    wavelength
    Electromagnetic energy is transmitted in the form of a sinusoidal wave. The wavelength is the physical distance covered by one cycle of this wave; it is inversely proportional to frequency.
