Cover Story: The aim of this study is to investigate a multimodal imaging system for monitoring retinal neovascularization using photoacoustic microscopy (PAM), optical coherence tomography (OCT), fluorescein angiography (FA), and color fundus photography. Retinal neovascularization was generated using intravitreal injection of the vascular endothelial growth factor (VEGF). PAM and OCT demonstrated changes in the retinal morphology and the spatial extent of retinal neovascularization. The multimodal-imaging platform performs imaging with a high lateral spatial resolution of 4.1 µm for PAM and 3.8 µm for OCT, with a high depth of penetration at a safe energy level. This allows for the visualization of retinal neovascularization and microvasculature morphologic changes after VEGF injection. Acquired PAM and OCT imaging provide 3D volumetric images of the vascular network that improve the characterization of the microvasculature in a safe manner in rabbit eyes.

The ability to establish the exact time a crime was committed is one of the fundamental aims of forensic science. The analysis of recovered evidence can provide information to assist in age determination, such as blood, which is one of the most commo...

It is sometimes desirable to implement filters using a transpose-form filter structure. However, managing image borders is generally considered more complex than it is with the more commonly used direct-form structure. This paper explores border hand...

Advancement in physics often results from analyzing numerical data and then creating a theoretical model that can explain and predict those data. In the field of lens design, the reverse is true: longstanding theoretical understanding is being overta...
