Hand-held apparatus for sideways driving of a tool

Hand-held reciprocating tool

An apparatus for making holograms of an object is described. The apparatus has a laser source emitting a collimated or slightly divergent laser beam, and a holder for a holographic plate to hold the holographic plate between said object and said laser source in a position near said object. A positive lens means having its focus is placed between said lens means and said holographic plate such that a divergent laser beam is impinging on said holographic plate and cover an illuminating area on said plate extending well beyond the area of said object in a plane parallel to said holographic plate. A closed housing is placed around said laser source and said lens means, which housing has a controllable shutter to be opened only at control provided in an end wall in a position cutting the beam path of said outgoing laser beam.
