Abstract:
1. A hybrid lidar-radar system for detecting the presence of tissue inhomogeneities within tissue by detection of reflected and scattered light signals from the tissue and discriminating information related to cancerous tumors from scattering of light created by the tissue itself, comprising: a source of microwave energy for providing a microwave subcarrier signal; a source of continuous wave light for providing and for transmitting toward the tissue an optical carrier signal that is modulated by the microwave subcarrier signal, said source of light transports the microwave subcarrier signal through the tissue and is reflected and scattered by the tissue, said optical carrier signal has a frequency and said source of continuous wave light comprises: a detector for detecting the scattered and reflected light and for producing electrical signals indicative thereof; and an optical detector that provides an output signal to a network analyzer that receives said produced electrical signals and measures phase and amplitude differences between the light scattered from the tissue and said optical carrier signal for the detection of said tissue inhomogeneities.
