Welcome to SPIE Security + Defence 2021

We look forward to gathering with you in person this September

Come to Madrid to learn and discuss the latest research


The Organising Committee of the 18th SPIE Security+Defence invites you to participate in this exciting meeting: this event crosses the divide between fundamental optical science and the application of the underpinning technologies in advanced defence and security systems.

This symposium will be co-located with the 28th SPIE Remote Sensing symposium, which enhances opportunities to identify new partners for collaboration from related fields of activity. Take the opportunity to learn about the latest scientific results in both topics “ Defence & Security” and “Remote sensing”.

Although we missed hosting the in-person conference in Edinburgh due to the global COVID-19 health crisis, we were grateful for the enthusiastic participation of over 1,880 academics, researchers, engineers, and scientists who were able to connect online during the Digital Forum. Amazing research was shared, products were demonstrated, and networking discussions had - thanks to your continued commitment to advancing science. 

This unique symposium will offer many opportunities to network with colleagues from a variety of disciplines in academia, industry, and government from all over the world, whilst still maintaining a distinctly European focus. SPIE Security+Defence will consider all aspects of this evolving field of optronics and photonics:

• Materials
• Optical devices
• Enabling technologies
• Advanced concepts
• Sensors (including their design, fabrication and exploitation)
• Micro- and Nanosystems in Security and Defence  
• Bio-inspiration and bio-mimetics
• Signal processing and control
• Laser technologies and their application
  (including high-power devices and applications)
• Electro-optic systems and concepts
• Modelling and simulation
• Quantum information science and technology
• Emerging security and defence requirements
• Target and background signatures
• Human observer performance
• Autonomy in sensing
• Cyber defence 
• Big Data in Security and Defence
• Artificial Intelligence and Machine Learning in Security and Defence

Other relevant topics are also welcome to ensure a vibrant meeting. Engineers and researchers from government, military, academia and the commercial sector will discuss current status and future directions of a wide range of R&D projects. Participation from academic institutes is especially encouraged; graduate and undergraduate student researchers are invited to submit their work and interact with international leaders. All papers presented at this event will appear in the SPIE Digital Library.

We look forward to seeing you at Security+Defence 2021 where opportunities abound for combining cutting-edge science and technology.
