Abstract: The invention includes methods and graphical interfaces to provide high dynamic range parameter adjustment in a graphical user interface by combination of a moving dial and moving scales in a single visual group. The motion of moving scales is opposite in direction to the motion of a dial moving in a direction defined by user input. Moving scales are translated by different amounts per amount of parameter value change to visually convey different magnitudes of change. The single dial indicates value in all of the scales, and the total value can be read to the precision of the most minor scale over a range of values of the most major scale by combined visual assessment of the multiple scales. The methods for graphical representation of values by a graphical scale group, and the governing rules for motion of the scales, are described.

Abstract: An optical homodyne detection scheme for FM chirped lidar is described. The system performs de-chirping within a photodetector, and it does not require high-speed photo-detection or RF mixing. Embodiments are also described for dealing with phase noise.
