The preferred embodiments of the present invention include a holography attachment device that is attachable to a digital imaging device to form a holographic microscope. The holography attachment device includes a chamber having at least one attachment mechanism to facilitate attachment of the chamber to a digital imaging device. The holography attachment device also includes a light source and a sample holder section, which is located between a proximate end and the distal end of the chamber. The light source is configured to radiate light within the chamber. The light passes through the sample holder section and impinges on an imaging sensor of a digital imaging device when the chamber is attached to the digital imaging device. The digital imaging device is capable of recording hologram information related to a sample held by the sample holder in the sample holder section.
