Abstract
The invention relates to a device and method for imaging electromagnetic radiation from an object. The device comprises entrance optics for allowing the electromagnetic radiation to enter the device, comprising an image plane onto which an image of the object is to be imaged. The device comprises an interferometer having a measurement arm, wherein the image plane is in the measurement arm. The device comprises a transformation layer, at the image plane, for transforming the electromagnetic radiation into a spatiotemporal variation of the refractive index of the transformation layer for causing spatiotemporal optical phase differences in the measurement arm of the interferometer that are processed to result in a representative image of the object.
