1. A device to measure hemodynamic parameters, the device comprising:

  • a first light emitting diode (LED) sensor configured to emit light at a first wavelength (λ

    1);

    a second LED sensor configured to emit light at a second wavelength (λ

    2), wherein the first LED sensor and the second LED sensor are covered with a collimated lens;

    a camera; and

    a processor configured to;

    control the camera to capture a first image of a plurality of images of a target region while the first LED sensor and the second LED sensor emit light on the target region;

    control the camera to capture a second image of the plurality of images of the target region while the first LED sensor and the second LED sensor emit light on the target region, wherein the second image is captured a predetermined time after the first image is captured; and

    determine one or more hemodynamic parameters based on a difference between at least the first captured image and the second captured image of the plurality of images.
