Abstract: A detection device includes: a light source that emits, toward an object, light of a first wavelength band, and light of a second wavelength band that is less readily absorbed by water than the light of the first wavelength band; a polarization splitter that splits at least one of S-polarized light and P-polarized light from light that has been reflected or scattered at the object; a photoreceptor that receives light reflected or scattered at the object via the polarization splitter; and a control unit that determines a state of the object from information based on light received by the photoreceptor. The light emitted by the light source is random polarized light where the ratio of P-polarized light and S-polarized light is generally uniform.

Abstract: An optical collection and detection system for use in a surface inspection system for inspecting a surface of a workpiece. The surface inspection system has an incident beam projected through a back quartersphere and toward a desired location on the surface, which is a scanned spot having a known scanned spot size. The incident beam impinges on the surface to create scattered light that is collected by a collector module. The collector module includes collection optics for collecting and focusing the scattered light to form focused scattered light. A collector output slit is positioned at an output of the collector module, through which the collection optics focus the scattered light. The scattered light that is associated with the scanned spot forms an imaged spot at the collector output slit. The collector output slit has a width that is selected to be proportional to the scanned spot size, so as to allow passage of the focused scattered light associated with the scanned spot, and exclude the focused scattered light associated with the workpiece regions other than the desired spot. A collector output varying subsystem varies the collector output slit so as to at least one of minimize passage of Rayleigh light scatter through the collector output slit or optimize a signal to air-scatter-noise ratio.
