Abstract: An optical power and gain detection apparatus including multiple optical power detection circuits, an FPGA device, and a temperature detection circuit. Various optical power detection circuits include a respective independent photoelectric converter, a trans-impedance amplifier, an analog signal conditioning circuit, a filter and an analog-digital conversion chip. By improving an analog circuit, digital detection and control in an optical amplifier, the property of the FPGA device may be used to realize the detection of optical signal and gain in a burst mode, avoid increasing complicated analogue circuits, and avoid the influence caused by element inconsistency in an analogue control solution. Whether the optical signal is in a stable mode or in a burst mode, the algorithm can detect the optical power accurately and stably, with a wide application range. By strictly controlling the synchronism of ADC sampling and the delay of calculation, the amplifier gain may be calculated more accurately.

Abstract: An apparatus feeds raw material bars to a furnace body of a melting furnace, and includes an enclosure body provided with a vertical feed passage to be disposed above an open top side of the furnace body. A feeding unit includes a push mechanism extending into an upper part of the feed passage, and a material retarder extending into a lower part of the feed passage. A transferring unit transfers a raw material bar to the feed passage in a manner that the raw material bar extends vertically in the feed passage. The push mechanism pushes the raw material bar in the feed passage downwardly, and the material retarder retards downward movement of the raw material bar out of the feed passage and into the furnace body.
