Search by keywords within the figure caption, article title, and author listing. Refine your search by using these guidelines on syntax, grouping, and wildcards:
Grouping. Separate search groups with parentheses and Booleans. Note the Boolean sign must be in upper-case.
Quotation marks. Use quotation marks to find words that must appear adjacent to one another; for example, the search "solid-state laser" will give results including both words together.
Wildcards. Improve efficiency in your search by using wildcards:
Filters. Use the filter options to narrow your search results. Users can filter by:
Grouping. Separate search groups with parentheses and Booleans. Note the Boolean sign must be in upper-case.
- (diode OR solid-state) AND laser [search contains "diode" or "solid-state" and laser]
- (photons AND downconversion) - pump [search contains both "photons" and "downconversion" but not "pump"]
Quotation marks. Use quotation marks to find words that must appear adjacent to one another; for example, the search "solid-state laser" will give results including both words together.
Wildcards. Improve efficiency in your search by using wildcards:
- Asterisk ( * ) -- Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity."
- Question mark (?) -- Example: "gr?y" retrieves documents containing "grey" or "gray"
Filters. Use the filter options to narrow your search results. Users can filter by:
- Journal -- Filter across OSA's traditional and Express titles.
- Volume/Issue/Page – Browse images within a specific volume, issue, and first page number.
- Date Range -- OSA will be adding more backfile content to the Image Bank on a regular basis.
- OSA Technical Divisions -- Based on OSA's 6 main topical divisions.
- OCIS Code -- Images can be filtered based on the source article's OCIS keywords.

(Top row) Subsampled complex-valued hologram data along the spiral path. The magnitude and phase values are represented by the saturation and hue, respectively, as shown in the color wheel of the legend. Undefined hologram pixels are displayed as the gray color. The corresponding numbers of spiral revolutions p, compression ratio M/N, and the reconstruction performance score (SSIM) are shown in Table 1. (Bottom row) The reconstructed image shows the proximal layer in red (z1=870 mm) and the distal layer in blue (z2=1070 mm). Empty space is depicted as white. (Inset) The zoomed-in view of the restored 3D object. Note the high quality of letter “S” down at the 25% compression ratio. |
