摘要： The invention concerns an electronic method for extracting the amplitude ES and the phase φS of an electrical signal in a synchronous detector, the signal containing a modulated part Imod of the form Imod∝ES f(t)*cos(φS−φR(t)), where φR(t) and f(t) are two known temporal modulation functions. The method comprises the following steps: multiplying the signal by two reference signals C(t) and S(t) constructed from φR(t) and f(t); integrating the resulting signals over a time tint; determining the amplitude and phase of said signal from the quantities X and Y resulting from the previous integrations. The method is characterised in that: said electrical signal is multiplied by C(t) and S(t) that can be decomposed on the same set of frequencies as those present in Imod. The invention also concerns the application of the above method in interferometric circuits and the use and execution of the above method.

摘要： A system and method is described for identifying a photographic camera model from a photograph taking the form of a compressed image that has undergone post-acquisition processing and fulfilling a linear relationship between the expectation and the variance of the pixels, such that σ2ym,n=aμym,n+b. The system includes an image processing device that can supply an analytical relationship between parameters (α, β) from the model of the discrete cosine transform (DCT) coefficients and the parameters (a, b) of the camera in the form (I), such that the parameters (c, d) determine fingerprints that characterise a photographic camera model and depend on both the frequency (p, q) and parameters a and b. The system includes a device for carrying out statistical hypothesis tests on the DCT coefficients and a statistical analysis device for determining if the photograph was taken by the photographic camera model or by another photographic camera model.

摘要： A system and method are described for identifying a photographic camera model from a photograph taking the form of an optionally TIFF-compressed image and fulfilling a relationship between the expectation and the variance of the pixels of the image. This relationship is dependent, inter alia, on two parameters, “c” and “d”, and these two parameters determine a fingerprint characterising the camera model. The system includes an image processing device that can process the photograph to estimate parameters “c” and “d”. The system also includes a device for carrying out statistical hypothesis tests on the distribution of the pixels of the photograph and a statistical analysis device for determining if the photograph was taken by the camera model by comparing the “c” and “d” parameters obtained from the photograph and the known “c” and “d” parameters of the camera model.
