Abstract: A method of position control of an optical component relative to a surface is disclosed. The method may include: obtaining a first signal by a first position measurement process; controlling relative movement between the optical component and the surface for a first range of motion using the first signal; obtaining a second signal by a second position measurement process different than the first position measurement process; and controlling relative movement between the optical component and the surface for a second range of motion using the second signal, the second range of motion being nearer the surface than the first range of motion.

Abstract: A method involving providing incident radiation of a first polarization state by an optical component into an interface of an object with an external environment, wherein a surface is provided adjacent the interface and separated by a gap from the interface, detecting, from incident radiation reflected from the interface and from the surface, radiation of a second different polarization state arising from the reflection of incident radiation of the first polarization at the interface as distinct from the radiation of the first polarization state in the reflected radiation, and producing a position signal representative of a relative position between the focus of the optical component and the object.

Abstract: An optical system and detector capture a distribution of radiation modified by interaction with a target structure. The observed distribution is used to calculate a property of the structure (e.g. CD or overlay). A condition error (e.g. focus error) associated with the optical system is variable between observations. The actual condition error specific to each capture is recorded and used to apply a correction for a deviation of the observed distribution due to the condition error specific to the observation. The correction in one practical example is based on a unit correction previously defined with respect to a unit focus error. This unit correction can be scaled linearly, in accordance with a focus error specific to the observation.
