Abstract: RFID readers may be configured to supply power to tags during frequency hops. When a reader is supplying power to a passive RFID tag via a first RF waveform having a first radio frequency and determines that it is to frequency-hop, the reader may determine whether the tag requires power during the hop. If so, the reader begins (or continues) to synthesize a second RF waveform with a second radio frequency while also synthesizing the first RF waveform, and frequency-hops by transitioning from transmitting the first RF waveform to transmitting the second RF waveform such that the power transmitted during the transition is sufficient for the tag to operate.

Abstract: Disclosed herein are methods of tomographic imaging, the methods comprising emitting a beam of light from a light source to a sample and modulating the beam of light through a spatial light modulator configured to convert the beam of light to an Airy beam. The spatial light modulator can be rotatable and positioned at a first angle relative to the sample. The method can further obtain a first perspective view of the sample, rotate the spatial light modulator to a second angle relative to the sample, and obtain a second perspective view of the sample. Each of the perspective views can be generated by the Airy beam interacting with the sample on a focal plane. The method can then reconstruct a volumetric three-dimensional view of the sample using the first perspective view and the second perspective view.
