Special Issue Information

Dear Colleagues,

Optical measurement processes use light to make non-contact measurements of the properties of a test object. Optical measurement has the advantages of precision, speed and short response time. Optical measurements have a wide range of applications, such as microscopes, telescopes, sensors, etc. The combination of optical measurement and sensors undoubtedly opens up wider applications for optical measurement and plays an important role in science and engineering.

This Special Issue invites manuscripts that introduce “Recent Advance of Optical Measurement based on Sensors”. All theoretical, numerical, and experimental papers are welcome. Topics include, but are not limited to, the following:

  • Optical measurement and instruments;
  • Fiber optic sensing;
  • Optical imaging;
  • Spectral measurement;
  • Photoelectric sensing and applications;
  • Interferometric measurement;
  • Optical navigation and equipment;
  • Microscopy.

In space gravitational wave detection missions, a drag-free system is used to keep the test mass (TM) free-falling in an ultralow-noise environment. Ground verification experiments should be carried out to clarify the shielding and compensating capabilities of the system for multiple stray force noises. A hybrid apparatus was designed and analyzed based on the traditional torsion pendulum, and a technique for enhancing the sensitivity of the torsion pendulum system by employing the differential wavefront sensing (DWS) optical readout was proposed. The readout resolution experiment was then carried out on an optical bench that was designed and established. The results indicate that the angular resolution of the DWS signal in optical readout mode can reach the level of 10 nrad/Hz1/2 over the full measurement band. Compared with the autocollimator, the sensitivity of the torsional pendulum is noticeably improved, and the background noise is expected to reach 4.5 × 10−15 Nm/Hz1/2@10 mHz. This method could also be applied to future upgrades of similar systems. Full article
