Development of high-energy lasers with military potential is leading to the production of beam weapons that transfer coherent light energy to the intended target to cause structural damage. In the coming...

Space and avionics applications need a high level of reliability as they face extreme conditions in space. In order to develop components qualified for this application, engineers need to design high...

JULY 2010: The thought of terrorist attacks in Mumbai on Nov. 26, 2008 still sends chills down our spines. Be it the attack on a city that never sleeps or the...

Quadcopters are becoming more widespread because they are incredibly stable, fast and fun to fly. Newer technologies have allowed development of smaller and cheaper quads with vast capabilities. While a quadcopter...

Even though the big guns are expected to fire ‘intelligently,’ shells fly through the air. Turbulences, humidity and sudden gusts of air can alter the trajectory of the shells. They might...

Model rocketry is an interesting hobby. To have a safe and predictable flight, rocketeers must have keen interest and some experience in the field. Lack of insight into the underlying technology...

In this concluding part of the article, let us wrap up by learning some more about high-energy laser weapons. Beam combination of multiple lasers Power scale-up to ten to hundreds of kilowatts in...

Understanding optronic sensors and related sensor systems is essential to understanding the design and operation of a large number of defence systems. Hence this six-part article series starts with an overview...

  Underwater laser communication is a technique that employs laser propagation under water to transmit data from one point to another. The technology is useful where physical connections through fibre optic cables...

Space exploration vehicles like satellites, probes, shuttles and spacecrafts all rely on electronics. These electronic devices have to withstand for their working not only the extreme (very low to very high)...
