Forensic Imaging


 

The Forensic Imaging Unit (F.I.U.) provides Photographic and Video Imaging services for all disciplines within the Crime Laboratories as well as for Law Enforcement agencies and Attorneys throughout the State of Wisconsin. Items of evidence requiring further examination can be digitally recorded while maintaining a true and accurate record of the physical evidence.  

 

The F.I.U. utilizes specialized lighting techniques, hi-resolution imaging equipment and computer applications to record and recover information that is often not visible to the human eye. Additionally, the F.I.U. will examine and enhance submitted images and video; recovering detail from a variety of submission types.  Some examples include: images captured of impression evidence at a crime scene, video surveillance footage, images recovered from a suspects cameras or old damaged film recovered in a cold case file.
 
The F.I.U. analyzes, duplicates, produces and enhances images from various forms of media: ie: VHS tapes, Film, DVR recordings and many other forms of media or image capture devices.
