Fig. 1 (a) Measured distribution of dual-path Lissajous patterns on three mirrors. (b) The picture of the three mirrors MPC with dual-path Lissajous pattern. Trace gases are atmospheric constituents ...

Interferometry, deflectometry and profilometry are diagnostic tools frequently used in optical metrology to achieve highly accurate, non-contact and full-field measurements. Since the relevant ...

Q: What’s a common use of Lissajous figures? A: Calibration. Based on the idea that the nonlinearities of devices contain useful information, outputs from twin encoder detectors can be plotted against ...

The other day, I happened across an interesting blog (these used to be called a “column”) at the EE Times Test & Measurement Designline site. It showcased using your oscilloscope screen as a “written” ...

Microelectromechanical systems (MEMS) mirrors have revolutionised beam steering and image acquisition across fields from lidar sensing and biomedical imaging to optical displays. By integrating ...
