Claim 0:
1. A tunable Fabry-Perot cavity self-calibration method, comprising the following steps:
S1: irradiating a filter with incident light, and obtaining calibrated light with a fixed wavelength after the incident light is transmitted through a calibration filter film on the filter;
S2: gating the calibrated light via the Fabry-Perot cavity, and obtaining selected light after the calibrated light is transmitted through the Fabry-Perot cavity; and
S3: irradiating an image chip with the selected light for imaging, so that obtain an output signal,
wherein, in step S2, the calibrated light is selected by controlling a driving voltage for the Fabry-Perot cavity to obtain selected light.
