Two-step Holographic Imaging Method based on Single-pixel Compressive Imaging
Jun Li,Yaqing Li,Yuping Wang,Ke Li,Rong Li,Jiaosheng Li,Yangyang Pan 한국광학회 2014 Current Optics and Photonics Vol.18 No.2
We propose an experimental holographic imaging scheme combining compressive sensing (CS) theory with digital holography in phase-shifting conditions. We use the Mach-Zehnder interferometer for hologram formation, and apply the compressive sensing (CS) approach to the holography acquisition process. Through projecting the hologram pattern into a digital micro-mirror device (DMD), finally we will acquire the compressive sensing measurements using a photodiode. After receiving the data of two holograms via conventional communication channel, we reconstruct the original object using certain signal recovery algorithms of CS theory and hologram reconstruction techniques, which demonstrated the feasibility of the proposed method.

An alkaliphilic, moderately halophilic, bacterium, designated strain X10-1T, was isolated from saline-alkaline soil in Daqing, Heilongjiang Province, China. Strain X10-1T was determined to be a Gram-positive aerobe with rod-shaped cells. The isolate was catalase-positive, oxidase-negative, non-motile, and capable of growth at salinities of 0–16% (w/v) NaCl (optimum, 3%). The pH range for growth was 7.5–11.0 (optimum, pH 10.0). The genomic DNA G+C content was 47.7 mol%. Its major isoprenoid quinone was MK-7 and its cellular fatty acid profile mainly consisted of anteiso-C15:0, anteiso-C17:0, iso-C15:0, C16:0, and iso-C16:0. The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences showed that X10-1T is a member of the genus Bacillus, being most closely related to B. saliphilus DSM15402T (97.8% similarity) and B. agaradhaerens DSM 8721T (96.2%). DNA-DNA relatedness to the type strains of these species was less than 40%. On the basis of the phylogenetic, physiological, and biochemical data, strain X10-1T represents a novel species of the genus Bacillus, for which the name Bacillus daqingensis sp. nov. is proposed. The type strain is X10-1T (=NBRC 109404T =CGMCC 1.12295T).
