An agile optical imaging system for optical coherence tomography imaging using a tunable source comprising a wavelength tunable VCL laser is disclosed. The tunable source has long coherence length and is capable of high sweep repetition rate, as well as changing the sweep trajectory, sweep speed, sweep repetition rate, sweep linearity, and emission wavelength range on the fly to support multiple modes of OCT imaging. The imaging system also offers new enhanced dynamic range imaging capability for accommodating bright reflections. Multiscale imaging capability allows measurement over orders of magnitude dimensional scales. The imaging system and methods for generating the waveforms to drive the tunable laser in flexible and agile modes of operation are also described.

Agile imaging system

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 (a-n) and a DAQ system () externally clocked by frequency clock signals to perform high-speed multi-channel optical imaging of samples.
