摘要: A system and method for photo-thermal imaging of a lateral flow immunoassay (LFA) device are provided. The system includes an intensity modulated heat source directed at a surface of the LFA device to selectively excite chromophore particles of interest and a thermal capture device configured to capture thermal waves emitted from the surface of the LFA device as a radiometric signal. A computing device, in communication with the thermal capture device, receives the radiometric signal and executes lock-in demodulation to detect surface or subsurface inhomogeneities of the LFA device.
