Abstract: A device is for chromatic confocal measurement of distances to a plurality of points on a reflective surface of an object. The device has a light source that generates polychromatic measurement light and a light pattern generating device that generates a light pattern from the measurement light. A chromatically uncorrected objective generates images of the light pattern in image planes whose axial position is wavelength-dependent due to chromatic longitudinal aberration. The device further comprises a spectrometer, which spectrally analyzes measurement light reflected from the surface, and a pixel-wise digitally switchable spatial filter which has a plurality of pixels and either forms the light pattern generating device or is arranged in a plane optically conjugate to the static spatial filter. Each pixel can be converted into a first switching state, in which the pixel blocks measuring light. and into a second switching state, in which the pixel does not block measuring light.

Abstract: The disclosure is related to an apparatus and method for charged hadron therapy verification. The apparatus comprises a collimator comprising a plurality of collimator slabs of a given thickness, spaced apart so as to form an array of mutually slit-shaped openings, configured to be placed at a right angle to the beam line, so as to allow the passage of prompt gammas from the target, the collimator being defined at least by three geometrical parameters being the width and depth of the slit-shaped openings and a fill factor. The disclosure is also related to a method for charged hadron therapy verification with a multi-slit camera.
