| 1. A digital detection method for use in diffuse optical tomography, the method comprising:
obtaining an analog signal modulated to contain diffuse optical tomographic information by directing a light source at an
object and detecting the attenuated light exiting the object;
converting the analog signal into a digital signal; and
performing digital processing and lock-in detection on the digital signal using an embedded digital signal processor-based
detection module that includes a controller or programmable logic device to facilitate obtaining the diffuse optical tomographic
information from the digital signal; and
transmitting the obtained diffuse optical tomographic information in digital form to a host computer for display and storage.
