Abstract: The present invention proposes a method for producing an authenticable moiré shape that simultaneously moves and shows a beating effect. The method relies on a combination of the 1D or the 2D moiré and the level line moiré. When tilting a compound showing such a moiré, the moiré shape moves, its intensity levels change significantly but its shape remains the same and is recognizable. Embodiments comprise a base layer made of patterned metallic tiny shapes and a revealing layer made of a 1D array of cylindrical lenslets or of a 2D array of spherical or aspherical lenslets.

Abstract: A system includes photodetectors each having a field of view and reflectors each respectively aimed at one of the fields of view. A beam-steering device is movable to different positions aimed at the different reflectors. A light emitter is aimed at the beam-steering device. The beam-steering device alternates aim between the reflectors to selectively illuminate the different fields of view.

Abstract: A flash lidar sensor assembly includes a first housing and at least one laser light source disposed in the first housing. The at least one laser light source is configured to generate a first field of illumination of light and a second field of illumination of light. The assembly also includes a second housing separate from the first housing. A first light receiver unit and a second light receiver unit are disposed in the second housing. The first light receiver unit is configured to receive light of the first field of illumination reflected off at least one object. The second light receiver unit is configured to receive light of the second field of illumination reflected off at least one object.

Abstract: An investigation and/or manipulation tool for a sample which is locally deformed when subjected to a local heat treatment includes a power supply for heating a tip of the tool wherein the tool has a structure such that the power supplied to the tip heats substantially only the tip of the tool and includes a region of relatively high heat conductivity that provides fast cooling of the tip when power is not supplied to the tip.

Abstract: The present invention concerns a cantilever arrangement for scanning a surface. This arrangement comprises a first cantilever having a first probe and a second cantilever having a second probe. Both cantilevers are mechanically coupled such that the second cantilever follows the movement of the first cantilever, i.e. the deflection of the first cantilever defines the deflection of the second cantilever.
