Abstract
A high-resolution handheld OCT imaging system related to the optical imaging field solves the issues of handheld OCT systems with low resolution and the inability to measure the skin's stratum corneum thickness accurately. Through adopting the visible wavelength band of supercontinuum laser as the light source, mainly applying reflectors instead of lenses in the OCT system, and replacing fiber propagation with optical propagation in free space in the interference optical paths, to significantly reduce dispersion loss in the axial resolution and improve the axial resolution of OCT systems. The filter, attenuator, grating, camera, and other components are separated from the handheld module through modular design to reduce the handheld terminal's size and weight and realize the system construction. The invention improves the axial resolution, obtains the thickness information of whole-body skin's stratum corneum, and provides technical approaches for skin diagnosis and related medicine development.
