Abstract: The present invention discloses an interference measuring apparatus, which comprises a light source module, a beam splitter, a first lens module, a reflecting module, a second lens module, and a detection device. A light beam generated from the light source module can be projected on the beam splitter. The beam splitter splits the light beam to generate a first light beam and a second light beam, wherein the first light beam passes through the first lens module and then projects onto the reflecting module, and the second light beam passes through the second lens module and projects onto an object. Furthermore, the first light beam and the second light beam are reflected by the reflecting module and the object, respectively, then both the first light beam and the second light beam are leaded to the detection device to form an interference pattern for obtaining the contours and internal cross-sectional image of the object.

Abstract: An optical amplifier includes an optical fiber having a core doped with transition metal ions, and at least one glass cladding enclosing the core. By using the fiber, the optical amplifier of the invention has a gain bandwidth of more than 300 nm including 1300-1600 nm band in low-loss optical communication.

Abstract: An automatic ROM burning device, comprising a support plate that is erected almost vertically. On the surface of the support plate is at least one feeder chute, inside which is inserted an IC rod, enabling the ROM component inside the IC rod waiting to be burned with data to lower in sequential order by gravity, while a moving mechanism moves it under the control of a control unit into a burner unit. The burner unit serves to conduct data burning and test operation on the components under the control of a control unit, and categorize the components according to the results obtained from the burning and testing operation. After data burning is completed, a moving mechanism delivers the components to a moving unit, moving the categorized components to separate discharge troughs; those of the same category are guided into empty IC rods for discharge.
