The invention discloses a detection method and device for a through hole, and the through hole is formed in a film layer. The detection method includes the steps that incident light is emitted to the inner wall of the through hole; first reflected light reflected by the inner wall and second reflected light reflected by the lower bottom surface of the film layer are received; an interference pattern is formed according to the first reflected light and the second reflected light; and parameters of the inner wall of the through hole are detected according to the interference pattern. The detection method achieves real-time detection on the through hole based on the light interference principle, and more importantly, the detection method does not need to destroy a product to be detected and therefore effectively saves economic cost.
