Abstract
A single snapshot multi-frequency demodulation method for a modulated image obtained by modulating and summing one or more original components at different frequencies in a time domain or spatial domain, especially for a modulated image including multiple frequency components. AC and DC component values of each pixel at each frequency are extracted sequentially, and then an original AC and DC component image corresponding to each frequency is obtained. The method can be used in the time or spatial domain, can decompose multiple frequency component images using single measurement, has the advantages of fast speed, higher demodulation precision and good de-noising effect, meets the requirements for acquiring multiple pieces of frequency information at a time and overcomes inevitable errors in multiple measurements. Further, multiple pieces of image information can also be transmitted once using the demodulation method, so that parallel real-time transmission of the information in the communication field is realized.
