Title: Length measuring apparatus for semiconductor laser
Inventor: WADA YORIO
IPC: G01B9/02
Filed: 1992-05-06
Abstract: PURPOSE:To enhance reliability by subjecting a semiconductor laser in a light source to temperature control or current control thereby stabilizing the oscillation wavelength and eliminating mode hop. CONSTITUTION:A light source 5 employs a distribution feedback type or distribution reflection type semiconductor laser which is subjected to temperature control through a Peltier element 6. Laser beam is emitted from the light source 5 to a beam splitter 10 where the laser beam is split into a transmission light and a reflection light. The reflection light impinges on an etalon 11 where the intensity of light is measured by means of an optoelectric converter 12 and current injection of the light source 5 is then controlled to stabilize the oscillation wavelength. A beam splitter 17 splits light beams, reflected on a moving reflector 4 and a reference reflector 15, into reflecting component and transmitting component. Each component is further split through a polarizing beam splitter 19 thence impinges on an optoelectric converting element 21 thus producing an interference signal. Interference light repeats light and dark as the moving reflector 4 moves. The repetition is counted by means of a counter circuit thus measuring the moving amount and moving direction of the moving reflector 4.

Filed: 1990-04-27
Abstract: PURPOSE: To obtain an EMI measurement system which can effectively distinguish narrow-band signals from wide-band or impulsive noise at a high speed by discriminating prescribed peaks based on test results obtained from an integrating means and a curve-fitting means. CONSTITUTION: When a signal 480 is inputted to a spectrum analyzer or an EMI sweep tuning receiver 500, the receiver 500 obtains a frequency spectrum 520, the RBW/frequency span of which becomes smaller than 70 or equal to 75 and is extended over a desired frequency span, by analyzing the signal 480 and inputs the spectrum 520 to a measuring means 540 which decides a discrete number of peaks in the spectrum 520. Each discriminated peak is supplied to an integrating means 580 for aspect ratio tests (initial discrimination). Each initial-discriminated peak is supplied to a curve-fitting means 620 for curve- fitting tests. Various peaks which passed both tests are classified as narrow-band continuous wave signals at 640. Therefore, the narrow-band continuous wave signals can be effectively discriminated from wide-band and impulsive signals at a high speed.
