Synthetic focal plane imager

摘要

A synthetic focal plane imaging system senses electromagnetic radiation as a distribution of energy over time rather than as a distribution of energy over space. A spatial context independent of the energy detection is developed. The synthetic focal plane imaging system includes an aperture, a mask, an electromagnetic sensor, and a computer configured to receive sample energy data and shutter modeling data from the mask to generate hyperspectral images. The synthetic focal plane imaging system incorporates a spiral rotating mask to create theta-space rotational masking architectures resulting in simple cyclical linear equations that can be processed quickly and efficiently to generate the hyperspectral images. The system captures image content at multiple wavelengths, electronically processes the resulting data as an image cube with stacked layers of images. Each layer corresponds to a particular wavelength of the imaged object with the same physical locations arranged on top of each other to form the stack.

1. A synthetic focal plane imaging system comprising:
an aperture configured to receive light; a rotary mask configured to rotate and to transform the light from the aperture into rotational coding periods of the rotary mask; a shutter position sensor configured to determine shutter sensor data including at least one of rotation speed, rotation direction, and rotation plane of the rotary mask; a single pixel electromagnetic sensor configured to receive the transformed light from the rotary mask and generate sample energy data based upon the transformed light from the aperture during the rotational coding periods of the rotary mask; and a computer device configured to receive the sample energy data and the shutter sensor data to generate hyperspectral images.
