Synchrotron radiation computed laminography (SR‐CL) has been in use in three‐dimensional non‐destructive imaging of flat objects for several years. A new set‐up is proposed based on the traditional SR‐CL method but with the detector inclined at the same angle as the sample inclination to collect projections. The results of computer simulations and real‐sample experiments demonstrate that reconstructions acquired using an inclined detector are of better quality compared with those acquired using ordinary detecting methods, especially for the situation of few projections and small difference of attenuation ratio of the sample. This method could be applied to obtain high‐quality images of weak‐contrast samples with short measurement time and mild radiation damage.
