%X Aiming to extract the veracity of the palmprint major line features under the non-contracting acquisition condition,this paper proposed a new palmprint images acquisition lighting source structure.It chose wavelength after the research of the spectrum absorbing and resonance scattering in the skin and blood.Designed one even lighting source by the research of the LED characteristics and the LED's distance proper arrangement.Comparing the lighting source of the same LED layout but the different wavelength wi...
