1. A method for determining a guided random data sampling, comprising the following steps:
S1, converting input data into an optical signal through a first conversion module, wherein an average intensity of the optical signal varies with a brightness of a light source, and converting the input data into the optical signal comprises converting an input signal into an analog signal and modulating an optical wave according to the analog signal;
S2, converting the optical signal into a guided optical signal according to guiding data by a photonic computing module, wherein the average intensity of the guided optical signal varies with the average intensity of the optical signal; and
S3, converting the guided optical signal into output data and outputting the output data by a second conversion module;
wherein a noise generated by at least one of the first conversion module, the photonic computing module, and the second conversion module is added to the output data as a perturbation, and
a ratio of the noise and at least one of an average intensity of the optical wave or an average amplitude of the analog signal decreases as the brightness of the light source decreases, thereby adding the perturbation to the output data.
