dc.descriptionThe data necessary to recreate the figures in the paper "Real-time millimeter wave holography with an arrayed detector" are organised into folders according the the figure name. data types are '.dat','.png' and '.avi' General notes - video format files output by the TeraView software, used for Fig S4 + visualisations and phase-shifting data are for some reason upscaled by the software to 128x128. Fig 2 - 3 x .dat image matrices, camera intensities recorded for the off-axis interferogram with no object ('beam'), reference beam only ('ref_r') and 2 PTFE plates interferogram ('plates'). Reference beam only is used to isolate the object amplitude following equation 1. Fig 3 - 1 x chopper_or_exp4_loop.avi, video of the in-line interferogram as the stage is translated, adding phase shift, pausing, then returning. For the reconstructions in the paper the data was taken from (time) index 50:150. - 1 x beam_or_loop.avi, as above with no object in place, used for normalisation. - 1 x ref_r_exp4.dat image matrix, intensity of just the reference beam used to extract the object amplitude following equation 2. Fig 4 - 4 x .dat image matrices for the off-axis data, camera intensities recorded for the off-axis interferogram with no object ('beam'), reference beam only ('ref_r') and plastic chopper (=Siemens star) interferogram ('plasChopper') and phase wheel ('wheel')). - 3 x .avi files for the plastic chopper, phase wheel and no object beam following the same format as for described for Fig 3. Fig S2 - 1 x No obj .png used for intensity normalisation. - 13 x ruler .png at horizontal translations as named. Fig S3 - 1 x plasChopper_or_exp4_loop.avi, the same data as in Fig. 4, used here to test sampling dependency. Fig S4 - 4 x .avi files corresponding to the video outputs from TeraView software. - 4 x .dat image matrix 'NoObj...' files contain stills of the interferogram when no object is present and could be used for normalisation (as opposed to the first frame of the videos) - 4 x .dat image matrix 'o_...' files contain stills of the object beam with reference blocked. - 4 x .dat image matrix 'r_...' files contain stills of the reference beam with object blocked. The .dat files may be used to determine the amplitude of the reconstructed object (compensate for ref intensity), but note that they use a different scaling to the video format .avi files.en_GB
