- All-optical clock recovery based on simultaneous external injection-locking and self-seeding of a Fabry-Perot laser diode
[作者:Fang, XH; Wai, PKA; Lu, C; Tam, HY; Qureshi, KK,期刊:OPTICAL ENGINEERING, 页码:25003-25003 , 文章类型: Article,,卷期:2011年50-2]
- We proposed and demonstrated a novel, simple, and low cost method for all-optical clock recovery based on the switching between two injection-locked longitudinal modes in a dc-biased multi-quantum-well Fabry-Perot laser ...
- Design of a fiber-collimated array for beam combining
[作者:Bellanger, C; Brignon, A; Toulon, B; Primot, J; Bouamrane, F; Bouvet, T; Megtert, S; Quetel, L; Allain, T,期刊:OPTICAL ENGINEERING, 页码:25005-25005 , 文章类型: Article,,卷期:2011年50-2]
- In this paper, we present the design of a very precise collimated fiber array that meets requirements for beam combining. Calculations permit to determine the tolerances toward key parameters and specify the components t...
- Twin-image elimination using quadrantal masks in a digital holographic microscope
[作者:Kim, M; Hong, S; Shim, S; Soh, K; Yu, Y; Shin, S; Kim, J; Kim, J,期刊:OPTICAL ENGINEERING, 页码:25801-25801 , 文章类型: Article,,卷期:2011年50-2]
- Holography has a considerable advantage of retrieving three-dimensional information of an object from only one interference recording. However, twin images always appear in the reconstruction for the reason of symmetry. ...
- Extracting targets from regions-of-interest in infrared images using a 2-D histogram
[作者:Park, CW; Lee, JM; Kim, YM; Kim, Y; Song, TL; Park, KT; Moon, YS,期刊:OPTICAL ENGINEERING, 页码:27003-27003 , 文章类型: Article,,卷期:2011年50-2]
- We propose an effective method of extracting targets from a region-of-interest (ROI) in infrared images by using a 2-D histogram, considering intensity values and distance values from a center of the ROI. Existing approa...
- Low-memory-usage image coding with line-based wavelet transform
[作者:Ye, LN; Guo, JL; Nutter, B; Mitra, S,期刊:OPTICAL ENGINEERING, 页码:27005-27005 , 文章类型: Article,,卷期:2011年50-2]
- When compared to the traditional row-column wavelet transform, the line-based wavelet transform can achieve significant memory savings. However, the design of an image codec using the line-based wavelet transform is an i...
- Human confusion costs for object classification
[作者:Wu, Y; Liu, YL; Yuan, ZJ; Zheng, NN,期刊:OPTICAL ENGINEERING, 页码:27201-27201 , 文章类型: Article,,卷期:2011年50-2]
- Most of the traditional evaluation criteria of object classification are based on the error rate, assuming that the costs of different errors are equal. However, the subjective evaluation of the human vision system on su...
