    Opis:
    The paper presents modern sensor systems for sniper detection. Among such systems there are active and passive opto-electronic devices. Its primary advantage is the possibility to early recognize the threat, before the sniper is able to take the shot. Presented passive systems employ thermal cameras and advanced image processing algorithms to distinguish the sniper and muzzle blast signatures. Active systems, in turn, rely on the detection of laser radiation, retro reflected from pointed optics (optical sights and observation scopes). The paper presents basic technical and tactical characteristics of sniper detection devices, both standalone and included in multi-sensor detection systems.
    W artykule przedstawiono współczesne systemy detekcyjne przeznaczone do wykrywania snajpera. Wśród systemów tego typu, wprowadzanych na uzbrojenie wielu armii istotną rolę pełnia pasywne i aktywne systemy optoelektroniczne. Ich zaletą jest możliwość wczesnej detekcji zagrożenia, zwłaszcza przed oddaniem strzału przez snajpera. Przedstawione systemy pasywne wykorzystują kamery termowizyjne i zaawansowane metody analizy obrazu w celu wykrycia sygnatur snajpera i strzału z broni palnej. Systemy aktywne wykorzystują z kolei promieniowanie laserowe w celu wykrycia optycznych przyrządów celowniczych i obserwacyjnych. W artykule przedstawiono charakterystyki techniczne i taktyczne szeregu urządzeń optoelektronicznych przeznaczonych do wykrywania snajpera, pracujących jako samodzielne urządzenia bądź jako elementy składowe \\ieloczujnikowych systemów detekcyjnych.

    Opis:
    The paper presents a digest of chosen technical work results shown by young researchers from different technical universities in this country during the SPIE-IEEE Wilga 2011 symposium on Photonics and Web Engineering. Topical tracks of the symposium embraced, among others, nanomaterials and nanotechnologies for photonics and telecom, sensory and nonlinear optical fibers, object oriented design of hardware, photonic metrology, optoelectronics and photonics applications, photonics-electronics co-design, optoelectronic and electronic systems for telecom, astronomy and high energy physics experiments, JET and pi-of-the sky experiments development. The symposium is an annual summary in the development of numerable Ph.D. theses carried out in this country in the area of advanced electronic and photonic systems. It is also an occasion for young researchers to meet together in a large group (under the patronage of IEEE) spanning the whole country with guests from this part of Europe. A digest of Wilga references is presented [1-92].

    Opis:
    Wilga Symposium gathers two times a year, together around 300 young scientists active in advanced photonics, electronics and software systems, including Internet engineering. May 2012 marked a jubilee XXXth meeting in Wilga Resort. There were presented over 250 papers from nearly all technical universities in this country. The organizers present here a research survey of the WILGA Symposium work. Also a digest of chosen Wilga references is presented [1]-[39]. This paper is the second part of a concise review digest focused on optoelectronics, communications, multimedia and ontology of information technologies.
