Imaging with a laser photography camera during limited visibility

Abstract

Present systems for vision monitoring very often employ many different imaging devices working in various spectral ranges, e.g. visible (VIS), near infrared (NIR), infrared (IR). Every single spectral range delivers slightly different relevant information for the process of threats detection, recognition and identification. However, technology progress still does not satisfy every need. Finding new vision solutions, capable of imaging in very difficult conditions (adverse weather conditions, partial occultation of the observed scene) is still one of the most urgent and demanding task for researchers. One of the possible solutions is to use a camera employing a time-spatial framing method. This method is able to minimize the impact of adverse factors on the image acquisition process. A laser photography device (LPD) is a camera developed in the Institute of Optoelectronics, Military University of Technology working according to the time-spatial framing method. The paper presents the theoretical basics and initial results of the laser photography device tests. © 2014 Photonics Society of Poland.
