| 41. | OCT is based on low-coherence interferometry.
|
| 42. | In 1926, an ambitious ring interferometry experiment was set up by Henry Gale.
|
| 43. | This technique is known as live holographic interferometry.
|
| 44. | Surface displacement detection has been demonstrated with ultrafast optical beam deflection and with interferometry.
|
| 45. | Two stars are only resolved by speckle interferometry.
|
| 46. | :The " Interferometry " approach is more difficult-but vastly more accurate.
|
| 47. | Optical interferometry is very tricky business and requires considerable processing to get an image.
|
| 48. | Additional problems must be addressed before applications of seismic interferometry can become more widespread.
|
| 49. | He also started to work on speckle phenomenon and speckle interferometry using photographic recording.
|
| 50. | Correlation interferometry uses coherences of fourth-order and higher to perform stellar measurements.
