An interference filter characteristic that needs to be considered for designs is the sensor acceptance angle
With an acceptance angle
of [+ or -] 30 degrees, the probe can measure difficult-to-access features at a scanning speed of 1,000 points per second for rapid throughput.
The fit to the data taken for samples outside the IS above 300 nm provided estimates of the microsphere diameter, real part of the index of refraction, suspension concentration, and the instrument acceptance angle
In addition, the sensor incorporates wide acceptance angle
pixel technology, helping to maintain corner performance while ensuring a minimum module height.
The system features a high diffraction acceptance angle
, which makes it suitable for weak beam, tilting and other analytical experiments.
The signal-to-noise ratio (and thus achievable communications rate) depends on the data rate, contrast ratio, acceptance angle
, and spectral bandwidth of the modulator.
The sensor's three transmission and receiver units have an acceptance angle
of three degrees and, from about 100 yards away, scan the entire width of a three-lane motorway, detecting any vehicles ahead.
Alex Clarke, global alliance manager with Coventry, UK-based OAS said the antenna can provide an acceptance angle
of over 25% off center before the connection between devices fails while still achieving considerable performance benefits over current IR technologies.
Several mechanisms underlying the remarkable nighttime sensitivi ty have been identified: they are increased photoreceptor gain, decreased photoreceptor noise, decreased lateral inhibition, and increased photon catch as a consequence of an increased acceptance angle
for each ommatidium .
The detector acceptance angle
was set at [similar to] 0.
A more practical design employs a nonimaging secondary concentrator at the focal plane of the primary imaging element, where the secondary can provide an additional concentration factor so that the concentration of the combined system approaches the allowed limit for the appropriate system design acceptance angle
9 degrees of acceptance angle
, another industry first.
