Abstract: A system including an imaging device with a line of sight to an object, capable of producing a glare, which is to be captured in an image, a light source configured to illuminate a surface of the object, and an optical barrier positioned along the line of sight between the imaging device and the object, said optical barrier being sized and positioned to reduce reflected light off the surface of the object directed along the line of sight from being captured in the image. Methods are also disclosed.

Abstract: A system including an imaging device configured to capture one or more images of a designated area with illumination at a low optical transmission wavelength which makes a latent print or a contaminant within the designated area visible in a visible spectrum in the one or more captured images with clarity to determine an identification from the latent print or contaminant in the one or more images, and a computing system configured to create a three-dimensional image from the one or more images to provide a composite image of the designated area with the latent print or contaminant visible with clarity to determine an identification from latent print or contaminant in the composite image is disclosed. A method and a non-transitory processor readable storage medium are also disclosed.

Abstract: A laser apparatus and method are provided for generating optical pulses based on Q-switching controllable with a fast and reliable two-dimensional (2-D) spatial light modulator, such as a digital micro-mirror device (DMD). Temporal and spatial modulation may be applied to selectively control the Q-switching provided by the spatial light modulator. The apparatus and method may be optionally optimized with straightforward optical components to increase angular magnification of a beam incident on the spatial light modulator and thus effectively reduce the Q-switching time.

Abstract: A system including an imaging device with a sensor having at least two dimensions operating in a long wave infrared emission spectrum to collect images of a latent print or a contaminant at different illuminating wavelengths, a storage device comprising a database of known material spectra, and a processor configured to determine an absorption spectrum per image based on a detection of high contrast being associated with low optical transmission and a detection of low contrast being associated with a high optical transmission and to compare the determined absorption spectrum with the known material spectra to determine a material identification of the latent print or the contaminant is disclosed. A method and a non-transitory processor readable storage medium are also disclosed.

A method and another system are also disclosed.

Abstract: A system including a flash lamp configured to operate at least at a single pulse duration which is less than a shutter speed of an imaging device and a flash lamp pulse count controller configured to operate the flash lamp at a number of successive pulses as set by the count controller. The number of successive pulses is determined by an image exposure level taken by the imaging device with a shutter of the imaging device continuously opened as the flash lamp produces the number of successive pulses. A method is disclosed. A non-transitory processor readable storage medium, providing an executable computer program product, the executable computer program product comprising a computer software code that, when executed by a processor, causes the process to perform certain functions is also disclosed.
