Self-Coherent Camera: active correction and post-processing for Earth-like planet detection
SPIE Proceedings, 2008Detecting light from faint companions or protoplanetary disks lying close to their host star is a demanding task since these objects are often hidden in the overwhelming star light. A lot of coronagraphs have been proposed to reduce that stellar light and thus, achieve very high contrast imaging, which would enable to take spectra of the faint ...

Least squares self-coherence for sub-nGal signal detection in the superconducting gravimeter records
Journal of Geodynamics, 2009Abstract In this paper, we use superconducting gravimeter (SG) data recorded at three stations of the global geodynamics project (GGP) network, with good geographical distribution, to search for possible significant peaks in the gravity spectrum that are in the assumed period range of the Slichter triplet. Seven-year long series from Cantley (Canada),

A MHz-level underwater ultrasonic wave with the kPa-level pressure is detected by the time-stretched self-coherence system with a high speed and highly coherent swept laser, which is significant for ultrasound detection.

Narrow-bandwidth silicon photonic CROW filter for carrier-extracted self-coherent (CESC) detection
Optics LettersIn this Letter, we report a second-order silicon photonic (SiP) coupled resonator optical waveguide (CROW) filter with an ultra-narrow 10-dB bandwidth of 1.75 GHz and a high extinction ratio (ER) of ∼50 dB. By utilizing this CROW filter, we demonstrated an innovative self-coherent detection, called carrier-extracted self-coherent (CESC) detection.
