We present a transmitted wavefront measuring system of large optic modules based on Shack Hartmann wavefront sensor, aiming to perform optical metrology for rectangular laser slabs arranged in a 4-high by 1-wide matrix. This system is developed to perform high-accuracy measurement for extremely ...
The adaptive optics system for the second-generation Very Large Telescope-interferometer (VLTI) instrument GRAVITY consists of a novel cryogenic near-infrared wavefront sensor to be installed at each of the four unit telescopes of the Very Large Telescop
the proposed method can optimize the required spatial resolution and enable real time measurement capabilities.The feasibility of the proposed setup is demonstrated,followed by a theoretical analysis and experimental results.Our experimental results show that the phase error repeatability in the nanometer ...

PROBLEM TO BE SOLVED: To provide a transmitted wave front measuring apparatus for a lens, which can perform tilt adjustment for aligning the optical axis of a lens to be tested to an advancing direction of a laser beam without separately preparing a light source.金沢 浩...
PROBLEM TO BE SOLVED: To provide an off-axis transmission wavefront measuring apparatus with a simple structure which is capable of conducting an performance check for off-axis light from all directions around the optical axis of a lens to be checked in a short time.植木 伸明...
In the measurement of transmitted wavefront of spherical lens, the reference wavefront include the front sphere and the rear mirror. To overcome the limitation, a novel absolute method is proposed. The absolute wavefront of the tested lens was obtained by rotating once and shifting twice. The ...

Wavefront MeasurementYtterbium Glass LaserTime resolve wavefront measurement was proved to clarify cooling process of the highly pumped ytterbium glass. A Shack-Hartmann sensor and a flashlamp pumped Ti:sapphire laser were used for wavefront measurement and high intensity pumping. Temporal change of ...
