PSF Estimation of Space-Variant Ultra-Wide Field of View Imaging Systems

Ultra-wide-field of view (UWFOV) imaging systems are affected by various aberrations, most of which are highly angle-dependent. A description of UWFOV imaging systems, such as microscopy optics, security camera systems and other special space-variant imaging systems, is a difficult task that can be achieved by estimating the Point Spread Function (PSF) of the system. This paper proposes a novel...

Lensfree Fluorescent On-Chip Imaging of Transgenic Caenorhabditis elegans Over an Ultra-Wide Field-of-View

We demonstrate lensfree on-chip fluorescent imaging of transgenic Caenorhabditis elegans (C. elegans) over an ultra-wide field-of-view (FOV) of e.g., >2-8 cm(2) with a spatial resolution of ∼10 µm. This is the first time that a lensfree on-chip platform has successfully imaged fluorescent C. elegans samples. In our wide-field lensfree imaging platform, the transgenic samples are excited using a...

Wide field-of-view imaging spectrometer using imaging fiber bundles.

A field-of-view-folding approach is proposed to extend the field of view (FOV) of a dispersive imaging spectrometer after introducing several linear arrays of imaging fiber bundles to which to replace the slit. The fiber bundles can flexibly connect fore-optics with a spectrometer to yield an imaging fiber-optic spectrometer (IFOS). The technology of FOV segmenting and folding, which can decrea...

Assessment of vitreous haze using ultra-wide field retinal imaging

BACKGROUND Conventional fundus imaging has been used to assess vitreous haze (VH) in patients with uveitis. Ultra-wide field (UWF) retinal imaging that uses scanning laser technology has not been evaluated for the detection of VH. This pilot study evaluates the ability of UWF imaging in detecting VH. Patients with intermediate, posterior, or panuveitis were examined to assess the level of VH us...

Ultra-wide field imaging of bilateral idiopathic retinal dialysis.

To cite: Kumar V, Ravani RD, Kuthirummal N, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216212 DESCRIPTION A healthy 22-year-old man presented with decreased vision OD for 1 month. There was no history of trauma. Best-corrected visual acuity (BCVA) was 20/400 OD and 20/20 OS. Anterior segment OU was normal. Dilated fundus examination OD (figure 1A) ...
