A confocal technology based on polycapillary X‐ray optics is proposed to perform three‐dimensional energy‐dispersive micro X‐ray diffraction. A three‐dimensional energy‐dispersive micro X‐ray diffractometer based on a polycapillary focusing X‐ray lens (PFXRL) in the excitation channel and a polycapillary parallel X‐ray lens (PPXRL) in the detection channel has been designed. At , the lateral resolution of this diffractometer is 49.7 49.9 at 7.5 keV, and its depth resolution is 48.1 at 8.0 keV. The total resolution of this diffractometer in is 6.5% at 6.4 keV and .
