1. A surgical visualization system to analyze at least a portion of a surgical field, the system comprising:
a laser-light illumination source configured to illuminate at least the portion of the surgical field with laser-light;
a light sensor configured to receive reflected laser-light;
a field programmable gate array configured to transform information indicative of the reflected laser-light to information indicative of moving particles in at least the portion of the surgical field;
a display configured to display an image comprising at least the portion of the surgical field; and
a processor configured to:
determine to operate in a first mode;
based on the determination to operate in the first mode, control the display to display a first metric, wherein the first metric represents a present state of moving particles in at least the portion of the surgical field;
receive an input;
based on the received input, determine to operate in a second mode; and
based on the determination to operate in the second mode, control the display to display the first metric and a second metric superimposed on the image,
wherein the second metric represents an aggregated state of the first metric of the moving particles in at least the portion of the surgical field.
