| NAME |
SANGLOK OBSERVATORY PHOTOMETER-POLARIMETER
|
| TYPE |
POLARIMETER
|
| DESCRIPTION |
The single-channel photometer-polarimeter at Sanglok Observatory was built at theInstitute of Astrophysics of Tadjik Academy of Sciences. It allowedquasi-simultaneous photometric and polarimetric observations. The useble wavelengthrange was 0.35-0.75 microns. The polarimeter worked on the modulation principle witha rapidly-rotating polarizer as the analyzer. The rotation frequency of the polarizerwas about 33 revolutions per second. Four impulse counters were used to registrateimpulses during each quarter of a polarizer revolution. The total number of impulsesin four positions of the polarizer allow the derivation of the values of the Stokes Qand U parameters and hence the value of the degree of linear polarization and theposition angle. The observing procedure included consecutive measurements of anobject and a sky background near the object with the same diaphragm. To control thestability of instrument operation the measurements of a built-in signal generatorwere used.For more information, seeKayumov V.V., Kiselev N.N., Pushnin P.A., Rakhimov V.Yu., Siklitskij V.I., TarasovK.V., Chernova G.P., Yakutovich V.N.
