Lensmeter using a lateral shearing interferometer
, 2012 The use of a laser shear interferometer for checking the collimation condition within a lensmeter is proposed. The interferometer consist of a wedged glass plate which produces a shear along the ortogonal direction to the wedge; when the fringes at the ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser
Laser &Photonics Reviews, EarlyView.A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

Simultaneous ToF/FMCW LiDAR Using a Dual‐Mode Light Source in a Single Architecture
Laser &Photonics Reviews, EarlyView.A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual‐mode light source that alternately generates optical pulses and frequency‐chirped light within a single acquisition. By combining time‐domain ToF and coherent FMCW ranging, the system achieves high‐resolution ranging and velocity sensing while extending the measurable range beyond ...

Evaluation and assimilation of Arctic Weather Satellite data in the AROME‐Arctic forecast system
Quarterly Journal of the Royal Meteorological Society, EarlyView.The Arctic Weather Satellite (AWS), launched in August 2024, is a prototype for the future EPS–Sterna constellation of small satellites carrying an innovative microwave sounder. We present the first assessment of AWS in the regional AROME‐Arctic numerical weather prediction system, covering post‐launch calibration results and the impact of AWS ...
