The Firefly Camera Core uses a high operating temperature (HOT) Mercury Cadmium Telluride (MCT) array with a resolution of 640 x 512 pixels on a 16μm pitch. Firefly provides all of the processing and interface requirements to drive a multi-functional handheld thermal imager, including additional camera channels, combined into an infrared camera core.
HOT technology enables cooled medium wave imagers to offer far superior performance in a more compact solution than uncooled imagers for long range, hand held and weapon-mounted applications. Firefly based systems will provide greater Detection, Recognition and Identification (DRI) ranges in a package with lower Size, Weight and Power (SWaP). The unique power saving features ensure an image is available instantly throughout the mission. The revolutionary electronic architecture of Firefly brings a wealth of features adding new capabilities for the system integrator and end user.
Firefly is a native Android™ device and all image processing is performed in software with GPU acceleration. Firefly’s software can be customised to meet the requirements of specific applications, for example; customized image processing, machine vision algorithms, or integration of pre-existing Android software libraries for capabilities such as augmented reality. The software based architecture allows additional functionality to be developed quickly and rolled out to units in the field.
Firefly has all of the functionality expected in an Android device, including integrated 3-axis accelerometer and gyroscope, GPS, Wi-Fi, Bluetooth and USB 3.0. These interfaces allow real-time streaming of video between Firefly units or other suitable systems. In addition a large number of GPIO’s which can be configured as button inputs, digital control lines or configured as a number of standard interfaces including; I2C, SPI and RS232. These interfaces allow Firefly to control a wide range of peripheral devices such as laser rangefinders.
The presence of two additional camera channels allows Firefly to be used as the core of a multi-waveband imager. Combining multiple camera channels into one processing core allows image fusion and provides net SWaP-C savings. The combined software and hardware power management system allows Firefly to offer state of the art power efficiency.
