G253/40/100 Grating For National Defense Japan

Abstract - Harvard University

Abstract - Harvard University

A highly sensitive fiber-optic mechanical vibration sensor is constructed by using a cascaded long period fiber grating (LPG) based on an intensity modulation scheme. In the fabrication process, the cascaded LPG, which is composed of a pair of identical LPGs with a certain distance, is inscribed in a length of photosensitive single-mode optical

A future alliance against China that could alienate South Korea would push the South as well as the North into the arms of China, leading to a tight bipolar environment in Northeast Asia. The . will and should remain an ally of South Korea, deeply involved in the peace process on the Korean peninsula.

A new electrically controllable diffraction grating using

Abstract An electrically controllable diffraction (ECD) grating using a polarization reflection from an electro-optic (EO) material is proposed and investigated in the experiments. The fundamental characteristics of this ECD grating are given experimentally for a He-Ne laser.

Type 95 Ha-Go light tank - Wikipedia

The Type 95 Ha-Gō (九五式軽戦車 ハ号, kyūgo-shiki kei-sensha Ha-Gō) (also known as the Ke-Go) was a light tank used by the Empire of Japan during the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in the Second World proved sufficient against infantry but, like the American M3 Stuart light tank, was not designed to combat other tanks.

Reflection-type electrically controllable diffraction

Reflection-type electrically controllable diffraction

Using the reflection of linearly polarized light from electrooptic material with an interdigital arrangement of electrodes, an electrically controllable diffraction (ECD) grating has been constructed for a He–Ne laser. An intracavity modulation of 30% was obtained for a He–Ne laser by setting the ECD grating inside the resonator with an applied voltage of 50 V.

Optical Transfer Functions of the Three Types of Variable

Optical Transfer Functions of the Three Types of Variable

Abstract The diffraction-based and geometrical optics-based optical transfer functions (DOTF and GOTF) are calculated for three types of variable-spacing diffraction gratings. The three types are: (a) a conventional grating, (b) a holographically produced grating and (c) a mechanically ruled variable-spacing grating. They are mounted on a Seya-Namioka monochromator.

Vibration sensing with fiber Bragg grating | (2001

The intensity of laser light is modulated when reflecting back from a fiber Bragg grating (FBG) which is glued onto a PZT vibrator and expands/contracts as the vibrator vibrates. The wavelength of the laser light is tuned to the slope of the FBG reflectance curve as a function of optical wavelength
