The figure of merit for such instruments is the spectral throughput, i.e. the product of detected intensity and spectral resolving power.
But with the spectral power to come, like a carnal cloud, to men in their sleep, nights, and seduce them.
His spectral powers proven, the hooded marauder was prepared to make his getaway into the night.
Fourier estimation of spectral power in selected frequency bands, 3.
Because incandescent bulbs sold for "general service" all have fairly similar characteristics (same spectral power distribution), power consumption provides a rough guide to the light output of incandescent bulbs.
Being the derivatives of gravity, the spectral power of gravity gradient signals is pushed to higher frequencies.
The integration of the power spectral density over the frequency range will give the spectral power.
A gas-discharge lamp is capable of exceeding the spectral power of direct sunlight in the infrared, especially when pulsed.
The characteristics of thermal radiation depend on various properties of the surface it is emanating from, including its temperature, its spectral absorptivity and spectral emissive power, as expressed by Kirchhoff's law.
