DEVELOPMENT OF THE CRYOGENIC-OPTICAL SENSOR FOR | |||||
| PROJECT MANAGER: Vitaliy Yatsenko1, US COLLABORATOR: Panos Pardalos2 1Institute of Space Research NAS and NSAU, SummaryThe objective of the project is to substantiate, theoretically and experimentally, the possibility of the development and implementation of the competitive adaptive cryogenic sensitive element (SE) based on the magnetic levitation phenomenon, high-precision optical measurement of levitating probe mechanical coordinates, and methods of signal processing. Today, the remote sensing is one of the fastest growing technologies around. It is a multibillion-dollar industry and remote thematic images are routinely used in an increasing number of fields. Solution of many important practical problems depends on a large-scale usage of the measurement systems and underlying physical principles. These problems include monitoring of the natural resources based on the analysis of the gravity anomalies, studying of global geodynamic processes and evolution of the Earth gravity field, analysis of movement of the Earth poles, etc. High sensitivity measurements are also necessary for carrying out fundamental physical experiments (testing of metric gravity theories, physical experiments with probe, etc.). In spite of the existence of the considerable achievements in the area of gravity measurements some important aspects of the problem have not been solved yet due to the absence of the appropriate sensitive elements (SE) and sensors with the relevant parameters. The authors of the project are going to promote solution of the problem of the development and implementation of the high precision gravimetric devices.

The authors of the project are going to develop a competitive adaptive cryogenic sensitive element applicable to the gravity meter sensor intended for the measurement of the weak disturbances of the gravity field, study of their characteristics, investigation of the global geo-dynamic processes, and to the natural resource search systems. .
In order to solve the above-mentioned problems, it is proposed to theoretically substantiate the possibility of the development and implementation of the high sensitive gravity meter based on the magnetic interaction of the superconductive short circuit current coils, and to develop an experimental sample of the optical-cryogenic sensitive element (SE) to validate the results of the theoretical research. Preliminary estimations showed that the method can provide the potential device s ensitivity about 10–12 g. Expected sensitivity of the proposed device is in the range between 10–10 g and 10–11 g. The device will have a stable null-point, and will prove out the stable performance for the long time. At present time only the superconductive gravity meter can show such behaviour. . | |||||
