Abstract

Characteristics of images measured by continuous-wave functional near infrared imager was analyzed in this paper by means of Fourier analysis. It is shown that, as an information transfer channel, the imaging system acts as a low pass filter. Low frequency information of the biological system is received by the cw imager. Relationship between scattering coefficient and the transfer function of the sample subsystem is discussed.
