Laser speckle and its elimination

D Gabor - IBM Journal of Research and Development, 1970 - ieeexplore.ieee.org
“Objective” speckle arises from the uneven illumination of an object with a multiplicity of
waves that interfere at its surface.“Subjective” speckle arises at rough objects even if they …

Information processing using speckle patterns

M Françon - Laser speckle and related phenomena, 1975 - Springer
It was after the advent of the laser and its applications in holography that the attention of
research workers was attracted by the speckle effect which is produced when a diffusing …

Speckle reduction using multiple tones of illumination

N George, A Jain - Applied optics, 1973 - opg.optica.org
The occurrence and smoothing of speckle are studied as a function of the line width for a
highly collimated illuminating source. A general theory is presented for speckling in the …

Speckle reduction

TS McKechnie - Laser speckle and related phenomena, 1975 - Springer
The remarkable granular or peppery nature not present in ordinary light'which Rigden and
Gordon first observed was quickly recognised as being a major objection to the use of …

Speckle-free reconstruction in digital holography

F Wyrowski, O Bryngdahl - JOSA A, 1989 - opg.optica.org
Generally, speckles impair the reconstruction of digital and optical holograms of diffusely
scattering objects. With the help of an iterative method, it is possible to introduce diffusers in …

Autocorrelation function and power spectral density of laser-produced speckle patterns

LI Goldfischer - Josa, 1965 - opg.optica.org
When a diffuse surface is illuminated by a coherent monochromatic source such as a laser,
the illuminated area appears speckled. Exposing photographic film directly to the …

Elimination of speckle noise in holograms with redundancy

HJ Gerritsen, WJ Hannan, EG Ramberg - Applied optics, 1968 - opg.optica.org
Holograms made of diffusely reflecting or diffusely illuminated objects can be scratched,
spotted with dirt, and even broken into pieces without serious loss of information. This …

[图书][B] Laser speckle and related phenomena

JC Dainty - 2013 - books.google.com
Since the invention of the laser there has been a growing interest in the random speckle
pattern that is generated when light from this highly coherent source is scattered by a rough …
