Abstract
An optical imaging system includes an optical radiation source, a frequency clock module outputting frequency clock signals, an optical interferometer, a data acquisition (DAQ) device triggered by the frequency clock signals, and a computer to perform multi-dimensional optical imaging of the samples. The frequency clock signals are processed by software or hardware to produce a record containing frequency-time relationship of the optical radiation source to externally clock the sampling process of the DAQ device. The system may employ over-sampling and various digital signal processing methods to improve image quality. The system further includes multiple stages of routers connecting the light source with a plurality of interferometers and a DAQ system externally clocked by frequency clock signals to perform high-speed multi-channel optical imaging of samples.
