By leveraging the inherent shift-invariant property of Fourier optical systems, our phase masks maintain a selective augmentation of the target object during in-plane translations within the field of view (FoV) without explicit tracking algorithms. Our results demonstrate selective target highlighting based on object size or shape, enabling continuous real-time observation in microscopy systems.https://biocil.github.io/tr/publication/2026_bopex_hussein/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2026_bopex_hussein/To suppress inter-shot phase drift, we propose a phase bias equalization that leverages isotropic reference regions to align complex phases across Jones elements. Experiments on biaxially oriented polypropylene (BOPP) films yield retardance and fast axis maps in agreement. Imaging of mouse brain sections and human cornea further demonstrates robust visualization of anisotropic microstructures.https://biocil.github.io/tr/publication/2024_frbm_altun/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2024_frbm_altun/Our results demonstrate that under ambient oxygen conditions, H2O2 exhibited no significant influence on NO production. Subsequent exploration under physiological normoxia (5 kPa O2) revealed distinct oxidative stress levels characterized by reduced basal HyPer7 signals, enhanced H2O2 scavenging kinetics, and altered responses to pharmacological treatment.https://biocil.github.io/tr/publication/2023_jmems_tekin/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2023_jmems_tekin/In this study, we investigate the effect of fused deposition modeling printing direction on the effective Young’s modulus value of cantilevers.https://biocil.github.io/tr/publication/2021_electrica_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2021_electrica_toy/Here, the system follows an off-axis digital holographic imaging configuration for the acquisition of quantitative phase at single shot. The system compromises from the resolution and magnification of a traditional microscope for the size of visual field, ease of use, and relative cost due to the exclusion of sample stages. A software level stitching further enlarges the effective field of view.https://biocil.github.io/tr/publication/2020_jlt_cetindag/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2020_jlt_cetindag/We present an optical efficiency improved speckle spectrometer where a scattering metal wave-guide is utilized along with a conventional prism spectrometer.https://biocil.github.io/tr/publication/2019_oc_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2019_oc_toy/Here, a wedge prism based simple approach is introduced to acquire quantitative phase images on a standard microscope.https://biocil.github.io/tr/publication/2018_ptl_cetindag/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2018_ptl_cetindag/With the proposed spectrometer, implemented using a CCD camera, we demonstrate up to 17-pm resolution at 855-nm central wavelength and 756.5-nm wavelength range revealing a dynamic range of ~44 500.https://biocil.github.io/tr/publication/2016_ral_hong/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2016_ral_hong/Digital holography is used to track the three-dimensional position of a magnetic microrobot maneuvered in real time by means of an electromagnetic manipulation system.https://biocil.github.io/tr/publication/2013_nphoton_cotte/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2013_nphoton_cotte/We introduce a microscopic method that determines quantitative optical properties beyond the optical diffraction limit and allows direct imaging of unstained living biological specimens.https://biocil.github.io/tr/publication/2012_ol_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2012_ol_toy/In this Letter we propose a fast off-axis hologram autofocusing (AF) approach that is based on the redundant data elimination by the critical resampling of the contained complex field.https://biocil.github.io/tr/publication/2012_bopex_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2012_bopex_toy/We describe an optimized digital holographic microscopy system (DHM) suitable for high-resolution visualization of living cells under conditions of altered macroscopic mechanical forces such as those that arise from changes in gravitational force.https://biocil.github.io/tr/publication/2011_jbo_cotte/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2011_jbo_cotte/With different illumination phases, enhanced bandpass information content is demonstrated, and its spatial resolution is theoretically shown to be potentially signal-to-noise ratio limited.https://biocil.github.io/tr/publication/2011_bopex_cotte/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2011_bopex_cotte/We present a novel technique for three-dimensional (3D) image processing of complex fields.https://biocil.github.io/tr/publication/2011_ol_ferhanoglu/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2011_ol_ferhanoglu/Findings show that diffraction grating readout principle is not limited to translating sensors but also can be used for sensors with tilt or other deflection modes.https://biocil.github.io/tr/publication/2010_opex_cotte/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2010_opex_cotte/We demonstrate that complex deconvolution does not require any additional optics in the DHM setup while extending the limit of resolution with coherent illumination by a factor of at least 1.64.https://biocil.github.io/tr/publication/2010_jbo_pache/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2010_jbo_pache/The DHM analysis reveals cytoskeletal alterations similar to those previously reported with conventional methods, and in agreement with conventional brightfield fluorescence microscopy a posteriori investigation.https://biocil.github.io/tr/publication/2009_sa_toy/Sun, 01 Jan 2017 00:00:00 +0000https://biocil.github.io/tr/publication/2009_sa_toy/Thermo-mechanical detector arrays in the 160 x 120 array format are designed, fabricated, and tested.
