| 摘要 |
The invention relates to instrument-making and measurement technique and can be used for study of optical radiation at carrying out different metrological works. A trap-detector for study of optical radiation comprises four photodiodes that are placed in incident plane of primary optical beam to the first photodiode in sequence in path of optical bean at different angles one with respect to another, at that the light-sensitive surface of one of photo-diodes is normal to optical beam that falls on it. The technical result is in decrease of sensitivity of detector to the polarization mode and increase of accuracy of measurements. |
