Abstract:
     This invention discloses a photoelectric automatic balance system of an UV-strengthened electric scaling radiometer including a thermal releasing device, a preamplifier, a harmonic amplifier, a synchronization rectifier, a compensation integrator, a square modulator and a balance driver, in which, when said heat releasing device receives radiation, it outputs power difference electric signals to rise the DC voltage of the compensation integrator as well as the electric heating power via the preamplifier, the harmonic amplifier and the synchronous rectifier, when the two heating powers are equal, said heat releasing device does not output signals, said integrator inputs zero current and its output remains unchanged so as to realize regulating electric power equal to the optical power automatically.
