FIELD: measuring equipment. ^ SUBSTANCE: device has lighting and receiving light guides, first ends of which are connected respectively to light source and photo-detector, and second - to capsule, in which due to reflection from inner mirror light flow is transferred from light guide to receipt guide. Connection of light and receipt guides to capsule is realized via directed Y-like fiber-optic router, common input-output of which is held in capsule oppositely to mirror, which is made at end of rod, held by its opposite end at the bottom of capsule with space relatively to inner side surface of capsule. Capsule and rod are made of dielectric materials, different by their coefficients of temperature linear expansion. Capsule can be made of quartz, rod - of silicate glass, inner mirror - spherical-shaped. Common input-output of directed Y-shaped fiber-optic router in capsule is held by silicate glue. ^ EFFECT: possible use within area of effect of high-frequency fields. ^ 5 cl, 2 dwg |
