Abstract:
1. A swept electromagnetic radiation system, comprising: a semiconductor laser operable to generate electromagnetic radiation through a first range of wavelengths and a second range of wavelengths, wherein the first range of wavelengths and the second range of wavelengths are spectrally separated, wherein the semiconductor laser is directly electronically wavelength selectable to discretely move between the first range to the second range without continuously sweeping a region between the first range and the second range; an interferometer coupled to the semiconductor laser, wherein the interferometer includes a reference path and a sample path; a detector for receiving electromagnetic radiation returned from the reference path and the sample path, wherein the detector generates output signals corresponding to the received electromagnetic radiation; and a controller coupled to the detector and the semiconductor laser, wherein the controller selectively causes electromagnetic radiation to be generated in the first range and the second range and the controller processes the output signals to generate image signals.
