During the study of laser-scattering properties of machined surfaces, an interesting reflective characteristic has been observed. For a certain range of angles of incidence a stationary reflective pattern has been observed regardless of the angle of incidence. We explain the same by using geometric optics. The intensities calculated from the model are found to be in good agreement with the experimentally measured intensity of the scattered pattern.
