Recent advances have extended anthropometry beyond flexible tape measurements to automated three-dimensional optical devices that rapidly acquire hundreds of body surface dimensions. Three new devices ...
Small optic nerve head variations associated with progression of retinal nerve fiber layer defects may be detectable using Heidelberg Retina Tomograph parameters, according to a retrospective study.
Optical 3D metrology enables fast, non-contact surface roughness measurement of defects and roughness for precise ...
Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...
With the continuous advancement of photoelectric performance in major equipment and advanced instruments, traditional optical elements are increasingly inadequate to meet the demands of modern systems ...
Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...
A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...
Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a ...
