Embodiment Construction

[0011] The oral soft tissue detection device based on optical Doppler imaging, the specific implementation process is that the frequency-sweeping laser (01) emits a beam with a center wavelength of 1310nm and a bandwidth of 100nm, which is divided into 10 : 90 two beams of light, respectively enter optical circulator one (03) and optical circulator two (09); wherein the light of optical circulator one (03) 10% passes through three paddle polarization controller one (04) and scattering compensator one (05) is focused to the dielectric film mirror (07) by the focusing lens (06), and then reflected to the optical circulator one (03) according to the original optical path to exit, wherein it passes through the dispersion compensator one (05) and the three paddle polarization controller one The modulation compensation of (04) is used to match the sample light, thus forming the reference light path of the system. Another beam of 90% light passes through the optical circulator two (0...

Abstract

The invention provides an oral soft tissue detection device and an oral soft tissue detection method based on optical Doppler imaging, wherein an optical fiber type Michelson interferometer hardware system built by a frequency sweep laser with a central wavelength of 1310 nm and a phase resolution algorithm software system are adopted to achieve the imaging detection of a biological tissue three-dimensional structure and a microvascular blood flow velocity. The specific implementation process comprises that the backscattered light of an interferometer sample arm and the backscattered light a reference arm generate an interference signal at a coupler; a photoelectric balance detector receives the interference signal; a 12-bit data acquisition card performs data acquisition; a phase resolution algorithm performs information processing; image reconstruction is carried out to obtain a sample structure image and a microvascular blood flow velocity result; and the information is applied to clinical diagnosis and later treatment process detection on oral diseases by a doctor, so that the influence process of oral soft tissue diseases on the three-dimensional structure and the microvascular blood flow rate of the oral soft tissue diseases can be monitored so as to substantially improve the treatment success rate of the oral diseases.

Description

technical field [0001] The invention relates to an oral soft tissue detection device, in particular to an oral soft tissue detection device and method based on Doppler optical coherence tomography technology. Background technique [0002] The clinical manifestations (such as tissue structure ulcers, blood flow velocity, biomechanical properties, etc.) corresponding to oral soft tissue diseases (such as mucosal disease, gingival cancer, cleft palate, etc.) The collection, detection and analysis of the corresponding relevant clinical characterization parameters can help to obtain the pathogenesis and impact results of oral soft tissue diseases. The research on the mechanism of disease impact is an important means to understand, treat and prevent oral soft tissue diseases, and has great significance in clinical disease prevention, detection, and treatment effect monitoring. Researchers have listed it as an important topic in the field of clinical medicine. [0003] The impact...
