Reflective confocal microimaging system

Abstract

The invention provides a reflective confocal microimaging system. An optical fiber bundle, a 1 / 4 wave plate and an objective lens are accommodated in an integrated optical fiber hose, and are combinedwith a confocal imaging technology, and thus it can be achieved that the reflective confocal microimaging system is small and portable. Besides, a doctor can flexibly detect the lesion area of a patient and is not limited by limiting disadvantages of universal arms anymore, and the reflective confocal microimaging system has low weight, a large using degree of freedom, and a high image resolutionrate.

Description

technical field [0001] The invention relates to the field of design and manufacture of a confocal microscopic imaging system, in particular to a reflective confocal microscopic imaging system. Background technique [0002] Skin computed tomography imaging, also known as skin confocal, skin CT is an important tool for skin disease detection. At present, the principle of confocal is mainly used, and the laser point light source is used to replace the wide-field light source to illuminate the sample. At the same time, a pinhole is used to form a point detection in front of the detector. The illumination point and the detection point are conjugate with respect to the focal plane of the objective lens. Points outside the focal plane are not imaged at the detection point, which effectively suppresses the effects of stray light. Through the scanning mechanism such as the galvanometer or the translation stage, the three-dimensional scanning imaging in space is formed, and the three...

Problems solved by technology

[0003] However, the confocal imaging method has some disadvantages: 1) The laser wavelengths used are relatively small. Due to the diversity of skin components, there are large differences in the absorption and reflection characteristics of various components for different wavelengths of light waves, which will lead to the use of different laser wavelengths. The imaging effect is different when the wavelength is small, and the best imaging effect cannot be achieved for specific skin components if the wavelength is small; 2) The imaging depth is insufficient

The vivoscope product of American LUCID company has a large volume, and the structure of the imaging head is relatively rigid, which cannot realize flexible switching of the imaging area.
