We describe a fast figure metrology system designed for the several thousand mirror quadrants in the High Energy Focusing Telescope (HEFT) balloon experiment. HEFT's multilayer coated hard x-ray optics will have approximately 1 arcminute HEW and operate at 20-80 keV. The optics are a conical approximation to the Wolter I configuration. Our automated system can measure the axial figure error, in- phase and out-of-phase roundness errors of a mirror quadrant, and output their HEW contribution to the x-ray telescope. An optical laser scans a conical mirror in two cylindrical coordinate axes. A 2D position sensitive diode measures the reflected beam to approximately 4 arcseconds. The conical mirror can have >= 3 cm radius. We show the figure measurements of HEFT's aluminum foil and thermally formed glass substrates.
