Optical piezometer for complex investigation of solid, liquid and viscous-plastic materials at high pressure that includes high pressure chamber with sample, piston, indicator of displacement and holder. Indicator of displacement – optical, has cylindrical body, adjustment block, movable and fixed mirrors of interferometer that is connected to cylindrical body of optical indicator of displacement, laser module that is used as source of support radiation, tube of collimator in which collimator is placed, and photo-receiver, for decrease of noise, movable tube of indicator that is connected to movable arm of optical; indicator of displacement, light-division cube of interferometer that is between the stopper of the cube rigidly fixed to holder of the cube, and the piston for pressure formation is connected to piston pusher rigidly connected to holder of movable arm of optical indicator of displacement, at that the holder of fixed arm of optical indicator is rigidly connected to the support on which one installs high pressure chamber with optical windows in which pressure gauge is placed, and medium that transfers pressure of sample, as such one applies ployethyl-siloxane liquid. |
