Extended Data Fig. 2: Calibration of the optical potential barrier projected by a DMD from the density response measurement of atomic BEC.
From: Transition from an atomic to a molecular Bose–Einstein condensate
a, Images of in situ atomic column density with different central barrier heights determined by different fractions of micromirrors fDMD that are turned on in the DMD. b, Example measurements of the proportionality p(x, y) for six pixels at different locations. The solid lines are linear fits to the linear part of the data points, the slope of which gives p(x, y). Data values and error bars are estimated as in Fig. 2 from 9–11 measurements. c, Spatial dependence of the proportionality p(x, y). The upper and right panels are line cuts in the x and y directions crossing the peak value. Data values are determined from the fits and the errorbars represent 95% confidence interval.
