Elimination of systematic errors in two-mode laser telemetry
We present a simple two-mode telemetry procedure which eliminates cyclic errors, to allow accurate absolute distance measurements. We show that phase drifts and cyclic errors are suppressed using a fast polarization switch that exchanges the roles of the reference and measurement paths. Preliminary measurements obtained using this novel design show a measurement stability better than 1 micron. ...

synthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Analysis and Recovery of Systematic Errors in Airborne Laser System
Although some mature manufactures of airborne laser system (ALS) have been published for some years, however, in china, the development of ALS just is on the starting step. Shanghai Institute of Technical Physics (SITP), CAS is developing a new airborne laser instrument. It is the best difficult task to determining the systematic biases of ALS. The ultimate goal is to determine the master syste...
