ADC Lite

Tetracam


Overview


The ADC Lite is a lightweight (7 ounce) version of our ADC Air Camera. This model's light weight qualifies it as an ideal solution for applications in which weight is a critical factor (such as on board small-payload-carrying unmanned aerial vehicles). The ADC Lite contains a single 3.2 megapixel sensor optimized for capture of visible light wavelengths longer than 520 nm and near-infrared wavelengths up to 920 nm.  

The camera and its accompanying software, PixelWrench2, are ideally suited for capturing and processing multi-spectral images of crops and forests and studying a variety of eco-systems.

PixelWrench2 provides color processing of Tetracam RAW and DCM files, complex batch processing tools, the ability to extract a variety of vegetation indices and a comprehensive suite of image editing tools.  Refer to our Multispectral Crop and Application Database or Selected Readings for descriptions of example applications.


ADC Lite (with 8.0 mm Lens) Ground Resolution & FOV Examples


The ADC Lite's field of view (FOV) is laid out in a 4:3 format.  When carried in a manned or unmanned aircraft, the field of view increases as the above ground level (AGL) altitude increases.  As the altitude increases, the camera's ability to resolve individual details on the ground decreases.   With its standard 8.0 mm lens, when flown at altitude of 400 feet above ground level, this camera creates an image large enough to capture 1.85 acres at a resolution of less than two inches per pixel in a single shot! 


System Controls and Connections


                                                                                 ADC Lite Control

The ADC Lite is designed to maximize the endurance of small unmanned aircraft systems.  Consequently, the system omits the rear liquid crystal display and in-camera batteries of the ADC.  User control of the ADC Lite is accomplished through hierarchical system menus such as the one shown at left. These are accessible via the system software (PixelWrench2) running on a Windows computer connected to the camera through its USB interface. The system menus present users with a series of configuration choices.  Scrolling through and selecting these configures the camera.  The indented button atop the ADC Lite acts as a shutter release for the camera.
