Through numerous sample runs, [Dries] found that defocusing the laser to a spot size of 1.5mm at low power settings makes for a perfect threadless seam. The resulting test pockets are quite ...

The new methods can break traditional limits of optics and often give counter-intuitive results, such as sharper pictures by defocusing and improved signal detection by adding noise. Specific areas of ...

Thermo-optic phase tuners allow beam steering at a variety of angles. Another modern instrument, known as a beamformer, combines beam focusing and defocusing along with the steering and power ...

Sony states that this “large” sensor enhances image clarity, lowers noise in low light and gives you soft background defocusing. However, I didn't experience these advantages myself. Overall, the ...

Time until first shot is captured. Powerup to first shot was still sluggish compared to DSLRs, but improved over the ~2.0 seconds we measured for the A7R. Switching from Play to Record mode and ...

Time until first shot is captured. Powerup to first shot was sluggish compared to DSLRs, and slightly slower than the 1.5 seconds we measured for the A7R II. Switching from Play to Record mode and ...

Because a deviation from exact focus also contributes to the desired phase shift, this is combined with a certain amount of defocusing. Colloquially, we can say that the price for seeing anything ...

Other features include easy switching between 90° and 180° scattering geometry and defocusing optics, which is essential for colored samples that can be heated by the laser beam. The typical ...

HKBN Ltd (STU:2HK) reports strong EBITDA and cash flow growth, despite flat overall revenue and challenges in the residential sector.
