We describe a high-speed camera system for frequency domain imaging suitable for applications such as in vivo diffuse optical imaging and fluorescence lifetime imaging. 14-bit images are acquired at 2 gigapixels per second and analyzed with real-time pipeline processing using field programmable gate arrays (FPGAs). Performance of the camera system has been tested both for RF-modulated laser ima...

remote sensing using small spacecraft arising from multi-objective economic activity problems is getting more and more developed. these satellites require very accurate pointing to specific locations of interest, with high reliability and small latency. the space borne imaging systems always attempted to achieve the highest ground resolution possible with the available technology at the given t...

this study was conducted to determine the use of three-dimensional ultrasonography (3du) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3du of the eyes were done using a 5–12 mhz linear trapezoid transducer. 3du of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

We show that asymptotic lifetime-based fluorescence tomography can localize multiple-lifetime targets separated well below the diffuse point spread function of a turbid medium. This is made possible due to a complete diagonalization of the time domain forward problem in the asymptotic limit. We also show that continuous wave or direct time gate approaches to fluorescence tomography are unable t...

Using a Cramer-Rao analysis, we study the theoretical performances of a time and spatially resolved fDOT imaging system for jointly estimating the position and the concentration of a point-wide fluorescent volume in a diffusive sample. We show that the fluorescence lifetime is a critical parameter for the precision of the technique. A time resolved fDOT system that does not use spatial informat...
