dc.description.abstractPhysical evidence examination has only recently began to utilize sophisticated techniques and current technology. The detection of latent fingerprints and characterization of single fibers by laser illumination are areas of current investigation. In this thesis, an instrument that utilizes a laser for sample excitation and control circuitry for spatial resolution is described. Luminescence imaging of latent fingerprints and single fibers, as well as spatially resolved luminescence spectra, are presented. The instrument is tested for both spatial and spectral accuracy as well as spatial reproducibility. The future use of this instrument, in modified form, in computer interface applications is discussed. Although only applications to forensic analysis are explicitly treated, the described instrument is useful for surface analysis generally whenever fluorescence or Raman data are pertinent.
