Drone Thermal camera - Thermal imaging for drones

29/11/2017

Thermography has become an important topic for various industries like industrial and construction sectors. Over the years the need to have thermal inspection from the air has resulted in new developments where thermal cameras can now be used with unmanned aerial vehicles or drones.
Drone thermal camera can be used for thermo-graphic inspection of inaccessible buildings or power lines as well as for fire fighting and law enforcement jobs. The same technology can be used in several other applications, for research and development, aerial archaeology, nature and animal observance.
Prior to the use of drone thermal cameras, elevated photography tripods were installed at higher locations which can quite inflexible and required extensive effort. The drone can also use HD video downlink to send live thermal images to one or more monitors i.e. a monitor for the thermographer and to a tablet PC of the person controlling the drone.

Thermal camera Smartphone - Integrated thermal camera

22/11/2017

There are several popular smartphones available in the market these days which offer integrated thermal cameras. CAT phones offer their flagship product CAT S60 which is dubbed as the world's first smartphone with an integrated thermal camera. Thermal camera Smartphone uses an embedded thermal camera from FLIR named as Lepton Thermal Microcamera Module which is also the smallest and most affordable thermal imaging sensor in the market today.
Thermal camera Smartphone can be used for detecting heat loss around doors and windows, spotting moisture and missing insulation. They can also be used for identifying over-heated electrical appliances and circuitry and allows one to see in complete darkness thanks to thermal imaging sensors.
Thermal camera Smartphone can visualize heat thereby highlighting temperature contrasts. It can pick up heat and measure surface temperature from a distance up to 100 feet and can see through obscurants such as smoke thereby enabling its use for building professionals, emergency first responders, utility workers and sports enthusiasts to name a few.

Thermal camera Android - High tech apps for Android devices

15/11/2017

As we have discussed, a thermal camera can be extremely useful in a wide variety of applications for security, building inspections, border security etc. When we are talking about thermal camera for android devices, we take this to an all together different level of user experience and affordability.
There are several popular applications like Therm-App offered by the Israeli company Opgal whose main objective is to turn a Smartphone into powerful thermal cameras that can offer high resolution thermographs and long range night vision capabilities. The Therm-App provides a thermal imager with a resolution of 384x288 pixels. The lightweight and compact device fits different phone models.
The interchangeable lens system offers easy detection of faraway targets through its long range (19mm) lens and a wide view through the 6.8 mm lens. The temperature range covered by the thermal camera for Android devices may look limited as the operating range is between 5 to 90 degree Celsius, however based on the use one can swap lenses in case a longer or shorter detection range is needed.

Thermal Camera - A brief overview

8/11/2017

A thermal camera can be used to create images formed with the help of infrared radiation. This type of camera is extremely helpful to improve visibility in the absence of any light. Also known as FLIR or, Forward Looking InfraRed the wavelength at which the thermal camera works is usually 14000 nm.
There are various applications which make use of thermal cameras like border security, industrial security, perimeter security, coastal surveillance, airport security, building inspection and many more. The thermal energy is converted into visible images which are then represented in the form of thermographs.
There are usually two types of thermal cameras like un-cooled ones and the cryogenically cooled ones. The uncooled ones have in-built batteries, operate at room temperature with infrared detector elements, makes no noise and activates immediately. The second one is very costly and can be damaged due to rough use. Thermal camera would depict normal temperatures in gray scale and high temperatures in colour.

Infrared camera - Development of High Speed Cameras

1/11/2017

Infrared detection technology has seen a lot of development in recent years. Development in cooled mercury cadmium telluride MCT or, HgCdTe has helped Infrared cameras to be used in a wide variety of demanding applications. The infrared camera is now available with spectral sensitivity in the various bands like shortwave, mid-wave and long-wave.
There are different camera resolutions available as a result of mid-size and large-size detector arrays. Other important features which have improved for infrared cameras includes high frame rate, adjustable exposure time and event triggering. Sophisticated processing algorithms offer an expanded range for the infrared camera which helps in avoiding saturation and optimizes sensitivity.
Single band MCT detectors fall in one of the five spectral bands like Short wave infrared camera (SWIR) which are visible to 2.5 micron, Broad band infrared camera (BWIR) which are visible between 1.5 - 5 micron, Mid-wave infrared camera (MWIR) visible between 3-5 micron, Long-wave infrared camera (LWIR) visible between 7-10 microns, and Very Long-wave infrared camera (VLWIR) visible between 7-12 microns.
