摘      要：Visual near-infrared imaging equipment has broad applications in various fields such as venipuncture,facial injections,and safety verification due to its noncontact,compact,and portable ***,most studies utilize near-infrared single-wavelength for image acquisition of ***,many substances in the skin,including water,protein,and melanin can create significant background noise,which hinders accurate *** this paper,we developed a dual-wavelength imaging system with phase-locked denoising technology to acquire vein *** signals in the effective region are compared by using the absorption valley and peak of hemoglobin at 700nm and 940nm,*** phase-locked denoising algorithm is applied to decrease the noise and interference of complex surroundings from the *** imaging results of the vein are successfully extracted in complex noise *** is demonstrated that the denoising effect on hand veins imaging can be improved with 57.3%by using our dual-wavelength phase-locked denoising ***,this work proposes a novel approach for venous imaging with dual-wavelengths and phase-locked denoising algorithm to extract venous imaging results in complex noisy environment better.
