We present an algorithm for coherent diffractive imaging with phaseless measurements. It treats the forward model as a combination of and incoherent waves. The reconstructs absorption phase contrast that quantifies attenuation refraction waves propagating through object. requires or partially illuminations, several detectors to record intensity distorted wave passes object under inspection. div...

1. The optical transparency of unstained live cell specimens limits the extent to which information can be recovered from bright-field microscopic images because these specimens generally lack visible amplitude-modulating components. However, visualization of the phase modulation that occurs when light traverses these specimens can provide additional information. 2. Optical phase microscopy and...

GC-FID and HPLC-DAD were developed for determination of menadione (MN) and menadione sodium bisulphite (MSB). By means of each method, quantitative analysis of MSB in commercial pharmaceutical was performed in both direct analysis of MSB and analysis of MN by converting MSB to MN with sodium carbonate. GC-FID method was carried out on the HP-5 capillary column using nitrogen gas. HPLC-DAD metho...
