Zusammenfassung:The invention discloses a cover glass thickness detection device and method, an electronic device and a storage medium, and relates to the field of optical detection.An emission module emits emission light, beam-expanded light is formed through collimation and beam expanding and is received by a detection module, and an objective lens in the detection module enables the beam-expanded light to form incident light to be focused on the target surface of a cover glass; incident light is reflected by a target surface to form reflected light, the reflected light is collected by the detection module and transmitted to the detection module to form a converged light spot, an objective lens defocuses the target surface to obtain a defocusing amount, the light spot during defocusing is collected by the detector, the processing unit calculates the pixel offset of the light spot, and the pixel offset is calculated by the detection module. The pixel offset and the defocusing amount are fitted to obtain a preset offset rela
