摘要
A device for detecting defects on at least one surface may include: a source configured to emit electromagnetic radiation in at least one first spectral band; a video camera sensitive in at least one second spectral band; and a diffuser configured to intercept at least part of the electromagnetic radiation emitted by the source and to make more homogeneous a spatial distribution of intensity of the electromagnetic radiation over the at least one surface. The source may be further configured to project a beam of the electromagnetic radiation onto the at least one surface. An intersection of the at least one first spectral band and the at least one second spectral band may determine a spectral working band. A bandwidth of the spectral working band may be less than or equal to 200 nanometers (nm). The spectral working band may be between 300 nm and 1,100 nm.
