Abstract Frequency-modulated continuous wave (FMCW) light detection and ranging (LiDAR) is an emerging 3D technology that offers high sensitivity precision. Due to the limited bandwidth of digitizers speed limitations beam steering using mechanical scanners, meter-scale FMCW LiDAR systems typically suffer from a low frame rate, which greatly restricts their applications in real-time imaging dynamic scenes. In this work, we report high-speed based system, combining grating for with compressed...
Abstract Selective cellular transmigration across the microvascular endothelium regulates innate and adaptive immune responses, stem cell localization, cancer metastasis. Integration of traditional microporous membranes into microfluidic vascular models permits rapid assay events but suffers from poor reproduction permeable basement membrane. Current in these systems have large nonporous regions between micropores that inhibit communication nutrient exchange on basolateral surface reducing...
Abstract Conventional hemodialysis (HD) uses floor‐standing instruments and bulky dialysis cartridges containing ≈2 m 2 of 10 micrometer thick, tortuous‐path membranes. Portable wearable HD systems can improve outcomes for patients with end‐stage renal disease by facilitating more frequent, longer at home, providing physiological toxin clearance. Developing devices these benefits requires highly efficient membranes to clear clinically relevant toxins in small formats. Here, the ability...
We present a real-time spectral-scanning frequency-modulated continuous wave (FMCW) 3D imaging and velocimetry system that can produce depth maps at 33 Hz, with 48° × 68° field of view (FOV) 32.8-cm range. Each map consists 507 500 pixels, 0.095° 0.14° angular resolution 2.82-mm resolution. The employs grating for beam steering telescope FOV magnification. Quantitative depth, reflectivity, axial velocity measurements static printed variation target moving robotic arm are demonstrated.
We demonstrate a novel, to our knowledge, approach for phase-resolved coherent 3D surface imaging that utilizes synthetic wavelength phase-based ranging and line-scan off-axis holography. Our proof-of-concept system employs an akinetic tunable laser perform fast switching galvanometer mirror slow-axis mechanical scanning. Quantitative depth measurements of anodized aluminum plate 3D-printed calibration targets printed circuit board are demonstrated. Analyses both shot-noise limited...
A new take on membranes for vascular modeling. In article 1804111, James L. McGrath, Thomas R. Gaborski, and co-workers lithographically fabricate dual-scale (nano- micro-porous) from ultrathin (100 nm) silicon nitride nanomembranes to support human endothelial cell culture modeling at the lab bench. Micropores provide transmigration routes studying immune, cancer, stem egress through wall.
