Abstract: A technique and device for recording and copyingreflection holograms (Denisyuk's holograms) with asemiconductor laser, emitting in the visible spectralrange ($lambda $EQ 672 mm), are described.Superfine-grain silver halide Bulgarian materialsHP-650 are utilized, ensuring high values ofdiffraction efficiency without bleaching afterdevelopment. The major operating characteristics aredetermined and the possibility of holographic recordingof real objects with vertical and horizontalpositioning is demonstrated. The technique and devicecan find application in the realization of replicas ofmuseum items, unique and rare specimens in the premiseswhere they are stored, or archeological excavationfindings during excavation, without the need oftransporting the objects to the holographiclaboratory.!10
