Hybrid simulation for creating realistic scenes for signature assessment

To create a complete virtual scene with sufficient fidelity so it can be used for signature/camouflage assessment turns out to be complicated. Small differences in scene parameters can have a huge impact on the outcome and parameters are often unknown, which makes comparison with real environments/scenes difficult. Instead of fully virtual...

Lisa telescope assembly optical stability characterization for ESA

The LISA Optical Stability Characterization project is part of the LISA CTP activities to achieve the required TRL level for all of the LISA technologies used. In 2012 the LISA mission was reformulated and transferred to the New Gravitational Observatory (NGO), which has similar performance requirements. This activity targets the demonstration...

Now is the time for the sunsensor of the future

What started as an academic development in frame of the Dutch MicroNed program five years ago should culminate in the introduction of the smallest digital sunsensor available in (and probably outside) of Europe at the ICSO. At the ICSO, TNO plans to show for the first time a working mini-DSS, based on the APS+ chip. The sunsensor has been...

The European computer model for optronic system performance prediction (ECOMOS)

ECOMOS is a multinational effort within the framework of an EDA Project Arrangement. Its aim is to provide a generally accepted and harmonized European computer model for computing nominal Target Acquisition (TA) ranges of optronic imagers operating in the Visible or thermal Infrared (IR). The project involves close co-operation of defence and...

The FESTER field trial

An overview is given of the First European - South African Transmission ExpeRiment (FESTER), which took place in South Africa, over the False Bay area, centered around Simon's Town. The experiment lasted from April 2015 through February 2016 and involved continuous observations as well as periodic observations that took place during four...

Inference of vessel intent and behaviour for maritime security operations

Coastguard and Navy assets are increasingly involved in Maritime Security Operations (MSO) for countering piracy, weapons and drugs smuggling, terrorism and illegal trafficking. Persistent tracking of vessels in interrupted time series over long distances and the modelling of intent and behaviour from multiple data sources are key enablers for...

Remote non-invasive stereoscopic imaging of blood vessels: First in-vivo results of a new multispectral contrast enhancement technology

We describe a contactless optical technique selectively enhancing superficial blood vessels below variously pigmented intact human skin by combining images in different spectral bands. Two CMOS-cameras, with apochromatic lenses and dual-band LED-arrays, simultaneously streamed Left (L) and Right (R) image data to a dual-processor PC. Both...

An adjustment for five degrees of freedom as an alternative for a hexapod mechanism

Modem mirror optics often consists of a limited number of elements, in which many aberrations may be attacked by adjusting only one element in five degrees of freedom, i.e. all degrees of freedom except the rotation around the optical axis. When the adjustment has to be reusable and mass and stiffness are of importance, a hexapod mechanism is ...
