The Mini-MCA is a lightweight, compact version of Tetracam's MCA (Multiple Camera Array) system which it replaced. Like the MCA, Mini-MCAs are available in three models. These are identified as the Mini-MCA4, Mini-MCA6. The number in the model name identifies the number of cameras in the array.
Each Mini-MCA system contains 4 or 6 factory-aligned multi-spectral cameras. Each camera contains a customer-specified narrow-band filter that is inserted between the lens and sensor. With each exposure, 4 or 6 separate bands of visible or near-infrared radiation move through each camera's lens and filter to form a separate monochromatic image on the camera's sensor. The images from each camera in the array are simultaneously transferred to each camera's compact flash memory card for later access by the user.
Analysis of the combination of multi-spectral images captured during each exposure enables Mini-MCA users to identify plant stress factors, soil types, fertilizers, or insecticides; differentiate plant species or recognize other plant, soil or chemical conditions that are, in each case, able to be identified by their unique spectral signature. Mini-MCA systems are also used to graphically illustrate vegetation indices such as NDVI that are defined by relationships of specific narrow-band wavelengths. Additional information about observed vegetation may be derived from these.
Each sensor captures a 5.2 Megapixel image on the MCA4 and 7.8 Megapixel images on the MCA6
