Fast steering, high-resolution imaging system.
High-resolution imaging can be dramatically improved by combining a fast image stabilization system and variable aperture masking. We describe an imaging system that provides high-resolution images through an annular aperture using the unwanted low spatial frequency light for image stabilization. The annulus thickness and diameter can be selected to enhance the contribution of different spatial frequencies in the image at the expense of image exposure time.
