| Abstract: | To discuss the feasibility of using the visible-near infrared multi-optical path length spectroscopic information for measuring the concentration of the human urinary albumin,an automatic micro-displacement measuring device was designed,by which visible-near infrared multi-optical path length(0-4.0 mm) spectra of urine samples were obtained.The partial least square(PLS) was used to set up the models of visible,near infrared and visible-near infrared dual-band multi-optical path length absorption spectra of ... |
