摘要：

A technique and device for recording and copying reflection holograms (Denisyuk's holograms) with a semiconductor laser, emitting in the visible spectral range (lambda = 672 mm), are described. Superfine-grain silver halide Bulgarian materials HP-650 are utilized, ensuring high values of diffraction efficiency without bleaching after development. The major operating characteristics are determined and the possibility of holographic recording of real objects with vertical and horizontal positioning is demonstrated. The technique and device can find application in the realisation of replicas of museum items, unique and rare specimens in the premises where they are stored, or archeological excavation findings during excavation, without the need of transporting the objects to the holographic laboratory.
