Abstract
In this work, image quality and optical coherence tomography were studied. The results of the study show that there is a very significant difference between ultrasound and optical coherence tomography to produce an image with a different wave. To understand this, we studied the basic principle of optical coherence tomography in the Michelson interferometer using monochromatic and broadband sources. Time-domain and spectral-domain measurements, which exist at the detector level, are briefly described using a glass sample. The time-domain signal strength of the Michelson interferometer using a broadband source is a Gaussian envelope.

We have discussed the principles of OCT and the way OCT can be used like a Michelson interferometer
It is evident that the most important part of an OCT is the time domain and spectral domain. e time domain is based on a moving mirror, but the spectral domain is not based on this moving mirror; it is based on the Fourier transform of an electric field
Summary
Huang invented optical coherence tomography (OCT) in 1991, and it has since found various applications outside of ophthalmology. Optical coherence tomography (OCT) is a technique that is currently in use in medicine and biology and is capable of creating high-resolution and cross-sectional images of biological tissues [3]. Included in this category are both transparent tissues, including the eyes, and heavily scattering tissues, such as the skin [4]. Its roots can be traced back to early research on white light interferometry, the discovery of optical coherence domain reflectometry (OCDR), a one-dimensional optical detection technique, is credited with giving rise to the technology [10] It was initially designed for the purpose of detecting flaws in defective optical fibres and optical network components; its capacity to probe the eye as well as other biological tissues was quickly realized [11]. Time-domain and spectral-domain optical coherence tomography can be determined in broadband sources
