1. An electronic device for measuring physiological information, the device comprising:

  • one or more light emitters configured to emit light;

    one or more light sensors configured to detect a reflection of the emitted light and generate one or more signals indicative of the detected reflected light;

    a device component capable of forming dynamically reconfigurable apertures having a configuration to allow light to be transmitted from at least one of the one or more light emitters to at least one of the one or more light sensors, each aperture including a center location; and

    a processor configured to;

    dynamically adjust a separation distance between the center locations of at least two of the apertures; and

    determine the physiological information based on the one or more signals.
