摘要： When inspecting the presence of foreign matter on a surface to be inspected by scanning the surface with a light beam from a light source utilizing a scanning system, and receiving scattered light from the surface by a detector, a correlation is utilized between a signal representing first scattered light obtained from the detector when the light beam scans a first line on the surface, and a signal representing second scattered light obtained from the detector when the light beam scans a second line displaced from the first line by a predetermined amount in a direction orthogonal to the direction of the first line.

摘要： A light source portion having an acousto-optic element produces a laser beam of two light components having a frequency difference .DELTA.w and having registered polarization directions. The laser beam is subsequently divided by a half mirror. One of the divided laser beams is detected by a photoelectric detector as reference light, and a corresponding signal is applied to a synchronism detector. The other laser beam is projected by a scanning optical system to the surface of, e.g., an original to be examined to scan the same. At the position on the surface irradiated by the scanning light spot, the laser beam is modulated at a beat frequency .DELTA.w on the basis of optical heterodyne interference. A synchronism detector detects a signal corresponding to the scattered light from a particle or defect on the surface being examined, in synchronism with the frequency of the reference light, whereby the particle or defect can be detected with a good signal-to-noise ratio.
