A system and method for contactless multi-fingerprint collection is disclosed. The contactless multi-fingerprint collection system includes an imaging volume, a user interface configured to provide feedback to the subject regarding a proximity of a hand to a desired imaging location within the imaging volume, and at least one image capture device to capture images of each of the plurality of fingerprints at each of at least two different depths from the fingerprints. The contactless multi-fingerprint collection system also includes a processor coupled to the at least one image capture device that is programmed to generate a composite image and a contour map of each of the plurality of fingerprints from the images captured at the at least two different depths and generate a two-dimensional rolled equivalent image of each of the plurality of fingerprints from the composite image and the contour map.

In accordance with one aspect of the present invention, a method for recording holographic data in an optical data storage medium is provided. The method includes (i) providing an optical data storage medium including: (a) a thermoplastic polymer matrix, (b) a latent acid generator, (c) a non-linear sensitizer, and (d) a reactant including a latent chromophore. The method further includes (ii) irradiating a volume element of the optical data storage medium with an interference pattern, said interference pattern including an incident radiation having a wavelength and an intensity sufficient to cause upper triplet energy transfer from the non-linear sensitizer to the latent acid generator, thereby generating an acid, wherein the latent acid generator is substantially non-responsive to said incident radiation. The method furthermore includes (iii) reacting at least one protected chromophore with the acid generated to form at least one chromophore, thereby causing a refractive index change within the volume element; and (iv) producing within the irradiated volume element refractive index variations corresponding to the interference pattern, thereby producing an optically readable datum. An optical data storage medium is also provided.
