title = "Measurement and uniformization of power distribution on the prism for biomedical applications of mid-infrared, attenuated-total-reflection spectroscopy",
abstract = "To obtain uniform power distribution on the ATR prism for biomedical spectroscopy system, the power intensity mapping on the prism is precisely measured by using a newly developed probing technique. It is found that the distribution of QCL based system is less uniform than that of the FT-IR based system due to the high coherency of the laser beam. To homogenize the distribution, a lens is introduced to diffuse the light and the incident beam is inclined to increase the number of reflections in the prism. As a result, we confirmed that the measurement error of in-vivo experiments is suppressed. ",
