Method for generating near-infrared spectrum data based on pattern sequence

The invention discloses a method for generating near-infrared spectral data based on a pattern sequence, which comprises the steps of 1, establishing a data array taking columns and rows as variablesas a pattern sequence, wherein the pattern sequence takes the patterns as identifiers, and each pattern is composed of a matrix of on-off states of n*m units; 2, establishing a corresponding relationship between each pattern in the pattern sequence and the on-off state of a chip unit of a spectrograph, and transmitting information of the on-off states of n*m micro-mirror units determined in each pattern to the chip unit; and 3, respectively measuring near infrared spectrum data of a sample in each pattern to obtain the pattern sequence near infrared spectrum data of the sample. The method forgenerating the near-infrared spectrum data based on the pattern sequence has comprehensiveness, flexibility and selectivity, and different pattern sequences can be designed to obtain different data according to the requirement
