Analytical Technology

Optical coherence tomography provides sections of tissues in a noncontact and noninvasive manner. The device measures the time delay and intensity of the light scattered or reflected from biological tissues, which results in tomographic imaging of their internal structure. This is achieved by scanning tissues at a resolution ranging from 1 to 15 μm. OCT enables real-time in situ imaging of tissues without the need for biopsy, histological procedures, or the use of X-rays, so it can be used in many fields of medicine. Its properties are not only particularly used in ophthalmology, in the diagnosis of all layers of the retina, but also increasingly in cardiology, gastroenterology, pulmonology, oncology, and dermatology. The basic properties of OCT, that is, noninvasiveness and low wattage of the used light, have also been appreciated in analytical technology by conservators, who use it to identify the quality and age of paintings, ceramics, or glass. Recently, the OCT technique of visualization is being tested in different fields of dentistry, which is depicted in the article.

Oct Imaging

In swept-source optical coherence tomography (SSOCT), the swept-source stimulates system by a series of wavelengths in time sequence; a photo detector then collects all reflected/backscattered light from testing sample as the components of Fourier series. Due to the nature of the SSOCT, the processing in spectral domain can merge multiple swept-sources with different central wavelengths, which greatly increases the resolution of the OCT imaging. In the wavelength probing OCT, a standard broadband SSOCT system is used to extract the internal structure of the sample, and another narrow band light can be used to probe the spectral feature of the sample at the probing wavelength.
