Simple NIR instrument for diagnostic purposes

A noninvasive NIR instrument for diagnostic purposes is presented. It is specifically designed for clinical tests during exercise. The instrument makes use of the most modern optical components and a high performance front-end electronics to enhance the signal to noise ratio and to reject stray lighteffect. A new signal analysis is proposed. The main features are low noise, high stability and readability.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
