break current
The point at which decreasing current supplied to a laser results in the extinguishing of the laser discharge.
beam noise
->
noise current
Any noise or current fluctuation that prevents precise measurement of the signal current. Both dark current and signal current have random fluctuations that affect the arrival of pulses. Thermal...
beam deflection tube
An electron-beam tube in which the current to an output electrode is regulated by the transverse motion of the tube's electron beam.
beam position
In computer graphics, the point on the display screen where the electron beam is located before the display instruction is executed. On directed beam display points, vectors and other graphic...
binary on-off
Signal used in optical transmission systems to generate currents in a detector that are decoded with reference to a specified threshold.
bioelectricity
Bioelectricity refers to the electrical potentials and currents generated by biological processes within living organisms. These electrical phenomena arise from the movement of ions across cell...
bipolar
Refers to transistors in which the working current flows through two types of semiconductor material: N- and P-type. In bipolar transistors, the working current consists of both positive and negative...
Bragg spectrometer
->
ionization spectrometer
Also known as the Bragg spectrometer. A system used for the x-ray analysis of crystal structure. In the instrument, a homogeneous beam of x-rays is directed on the known face of a crystal and the...
breakdown voltage
In avalanche photodiodes, the point at which an increase in the reverse bias voltage causes the current gain to approach infinity.
