Abstract :
Frequency-domain NIR techniques have been widely used to study the physiological state of biological tissues non-invasively. This paper presents a theoretical model to predict and optimize the performance of frequency-domain system. Experimental data are demonstrated to validate this method. This model can be used to design and optimize frequency-domain system for various applications
