Abstract
The present disclosure describes systems and methods that use spatial modulation to focus continuous wave light into a localized region of interest such as an individual blood vessel. In certain embodiments, intensity modulation techniques, such as linear frequency modulation, are used in conjunction with spatial modulation to achieve more precise measurements through otherwise scattering medium. The focused beam of continuous wave light is capable of penetrating several centimeters of tissue to deliver measurements and images associated with individual blood vessels and other discrete vascular components.
