System and method for replicating volume holograms

A method for duplicating a hologram comprising:

• directing a coherent incident radiation beam at a first optical component;
• transmitting the coherent incident radiation beam through the first optical component forming a transmitted beam, to a second optical component having a hologram recorded therein;
• and
• diffracting the transmitted beam via the hologram forming a diffracted radiation beam, wherein the coherent incident radiation beam and the diffracted beam interfere within the first optical component to form a replica of the hologram therein.

A method for duplicating a hologram comprising:

• directing a coherent radiation beam at a first optical component having a hologram recorded therein;
• diffracting a first portion of the coherent radiation beam via the hologram forming a diffracted radiation beam;
• transmitting a second portion of the coherent radiation beam through the first optical component forming a transmitted beam;
• and
• interfering the diffracted radiation beam with the transmitted radiation beam within a second optical component to form a replica of the hologram therein.

A method for contact recording at least one hologram comprising:

• arranging at least a first master hologram and at least a first holographic blank in optical contact to form a master/blank assembly;
• exposing the master/blank assembly to a pre-recording beam;
• and
• exposing the master/blank assembly to a recording beam, wherein the master/blank assembly remains optically contacted throughout each exposure.

A method for contact recording at least one hologram comprising:

• arranging at least a first master hologram and at least first holographic blank in optical contact to form a master/blank assembly;
• exposing the master/blank assembly to a recording beam;
• and
• exposing the master/blank assembly to a post-recording beam, wherein the master/blank assembly remains optically contacted throughout each exposure.

A system for contact recording multiple holograms comprising:

• a first, second, and third master hologram;
• a first, second, and third holographic blank wherein the first, second, and third master hologram and the first, second, and third holographic blanks are in optical contact, forming a stack;
• and
• a first, second, and third recording beam, wherein when the first recording beam is incident upon the stack, the first master hologram is ON and the second and third master holograms are OFF, forming a first replica hologram of the first master hologram in the first holographic blank;
• when the second recording beam is incident on the stack, the first and third master holograms are OFF, the first replica hologram is OFF, and the second master hologram is ON, forming a second replica hologram of the second master hologram in the second holographic blank;
• when the third recording beam is incident on the stack, the first and second master holograms are OFF, the first and second replica holograms are OFF, and the third master hologram is ON, forming a third replica hologram of the third master hologram in the third holographic blank.

A method for contact printing multiple master holograms comprising:

• providing a stack comprised of first, second, and third master holograms and first, second, and third holographic blanks that are in optical contact;
• switching ON the first master hologram;
• exposing the stack with a first recording beam, forming a first replica hologram within the first holographic blank;
• switching OFF the first master hologram and switching ON the second master hologram;
• exposing the stack with a second recording beam, forming a second replica hologram within the second holographic blank;
• switching OFF the second master hologram and switching ON the third master hologram;
• and
• exposing the stack with a third recording beam, forming a third replica hologram within the third holographic blank.
