Introduction Coherent spontaneous hemodynamic fluctuations have been widely observed in many brain networks of different species, and they were hypothesized to reflect underlying “functional connectivity” [1] of the brain and imply many “resting networks” . Since it is known that the anesthesia can significantly affect brain activity and state; it can probably also influence these resting netwo...

We report on amplitude and phase imaging of out-of-plane sinusoidal surface vibration at nanometer scales with a heterodyne holographic interferometer. The originality of the proposed method is to make use of a multiplexed local oscillator to address several optical sidebands into the temporal bandwidth of a sensor array. This process is called coherent frequency-division multiplexing. It enabl...

D1 magic wavelengths have been predicted for the alkali atoms but are not yet observed to date. We experimentally confirm a wavelength that is lie at 615.87 nm $^{23}$Na, which we then use trap and image individual with 80.0(6)% efficiency without having modulate trapping imaging light intensities. further demonstrate mean loading remains as high 74.2(7)% 1D array of eight atoms. Leveraging on ...

Recently, coded masks have been used to demonstrate a thin form-factor lensless camera, FlatCam, in which a mask is placed immediately on top of a bare image sensor. In this paper, we present an imaging model and algorithm to jointly estimate depth and intensity information in the scene from a single or multiple FlatCams. We use a light field representation to model the mapping of 3D scene onto...
