Abstract: This application relates to the technical field of confocal microscopy measurement, and provides a dark-field confocal microscopy measurement apparatus and method based on multi-fractional angular momentum demodulation. The apparatus includes a modulated illumination module and a signal collection and demodulation module. The modulated illumination module obtains vortex light with different fractional orders through modulation using vortex phase patterns with different fractional orders, so as to scan a to-be-measured sample. The vortex light with different fractional orders irradiates the to-be-measured sample and is reflected out. The signal collection and demodulation module collects the reflected light and generates dark-field images, and finally performs cross-correlation processing on the dark-field images generated under the vortex light with different fractional orders, to obtain high SNR data.

Abstract: Provided are a dark-field confocal microscopy measurement apparatus and method.
