Differential optical shadow sensor for sub-nanometer displacement measurement and its application to drag-free satellites
Andreas Zoellner, Si Tan, Shailendhar Saraf +4
We present a method for 3D sub-nanometer displacement measurement using a set of differential optical shadow sensor. It is based on using pairs of collimated beams on opposite side…
Ground Testing and Flight Demonstration of Charge Management of Insulated Test Masses Using UV LED Electron Photoemission
Shailendhar Saraf, Sasha Buchman, Karthik Balakrishnan +15
The UV LED mission demonstrates the precise control of the potential of electrically isolated test masses that is essential for the operation of space accelerometers and drag free…
UV LED charge control of an electrically isolated proof mass in a Gravitational Reference Sensor configuration at 255 nm
Karthik Balakrishnan, Ke-Xun Sun, Abdul Alfauwaz +15
Precise control over the potential of an electrically isolated proof mass is necessary for the operation of devices such as a Gravitational Reference Sensor (GRS) and satellite mis…
