Abstract

The miniature cameras are the critical equipments to support the low-cost Micro Air Vehicles or small satellites for earth observation and many other applications. So a miniature imaging system with high resolution and large area array was proposed in this paper. Firstly

the target sampling distance and swath width were estimated for the designed imaging system. Then the electronic scheme of the system was described

where the working principle of the key chip OV14825 was introduced

and the software design based on FPGA was analyzed for serial differential data receiving and forwarding. Finally

imaging experiments were carried on the designed camera. The resolution was better than 0.5 mm when imaging in the 13 m distance

and the obtained images were rich in details

which proved that the scheme was feasible. And the miniature cameras with high resolution and large area array were of great value.
