Summary:An apparatus and method for inspecting an object by optical triangulation, where the signal of interest in a captured image corresponds to an interaction between a light beam and an environment surrounding the object rather than between a light beam and the object itself. The surrounding environment may be configured to interact in a manner that is detectable by filling it with a flowable scattering medium, e.g. a gas, mist or vapour comprising a suspension of fine particles in air. Light that is scattered by the flowable scattering medium is visible in a captured image. Where the flowable scattering medium is not present, e.g. because the object blocks it, the scattered signal is less. A boundary of a scattered signal region may thus provide information about the location of an object.
