Abstract: Different type of the neutrino detection technics and the structure of the neutrino detectors in the famous experiments are reviewed and investigated in this course. The course consists of SNO, Super-Kamiokande, Ice-Cube experiment and their detailed structure of detectors. The detailed electronics, materials, and the fundamental of the operation of the detectors are presented here. Some of the main complexities in the detection of neutrino properties are also discussed in the course. Finally, some of the last results in the detection of neutrinos are reviewed.
