Title: Flaw inspecting apparatus
Inventor: KOIZUMI MITSUYOSHI
IPC: G01N21/95
Filed: 1980-02-25
Abstract: PURPOSE:To eliminate the effect of the cutter mark and facilitate the discrimination between linear and lone flaws by a method wherein a plurality of photodetectors to detect the irregularly reflected rays from the sample surface are arranged in the circumferential direction of the sample surface, and the irregularly reflected ray intensity is partitively detected. CONSTITUTION:A plurality of photoelectric tubes 61-6n are annularly arranged facing the sample 4 surface. The photoelectric tubes 61 and 6m face in the direction of the principal component of the irregularly reflected rays from the cutter mark. The irregularly reflected rays from a linear flaw are in the direction of the photoelectric tubes 65 and 6n. In this case, the linear flaw can be highly sensitively detected by the outputs of the photoelectric tubes 65 and 6n. This is because the nonprincipal component of the irregularly reflected rays from the cutter mark is made incident on each of the photoelectric tubes except for the photoelectric tubes 61 and 6m, being dispersed. In the case of a lone flaw, because the directivity of the irregularly reflected rays is weak, all the photoelectric tubes except 61 and 6m have the approximately same output. In the case of a flaw parallel to the cutter mark, the irregularly reflected rays are made incident on only the photoelectric tubes 61 and 6m. Thereby, the linear and lone flaws can be readily discriminated.

Title: Strength modulating frequency variable light source
Inventor: TACHIKAWA YOSHIHIKO
IPC: G01M11/00
Filed: 1995-02-10
Abstract: PURPOSE: To realize a linear sweeping control of a modulating frequency, by delaying a part of the output light or a modulating signal of an E/O converter adequately by a delaying circuit, and detecting the variation amount of the modulating frequency per unit time. CONSTITUTION: The light output from an E/O converter 1 permeates through an isolator 4 and a beam splitter 5, and outgoes to the outer side. The light branched by the beam splitter 5 permeates through an optical fiber 6, and it is detected by a light detector 7. Since the output of the light detector 7 generates a specific time difference between the output of the light detector 7 delayed by the optical fiber 6, and the output of a distributor 16, a signal with the frequency equal to the product of the difference of the modulating frequency converted in the delaying time, that is the tendency of the variation of the modulating frequency (the variation amount of the modulating frequency per unit time), and the delaying time by the optical fiber 6, is output from a mixer 8.  A control circuit 12 outputs a control signal to make constant the frequency of the signal output from the mixer 8 by the output of a phase comparator 11. Consequently, the modulating frequency of the light strength can be sweeped directly.

Title: Optical frequency modulation method
Inventor: EMURA KATSUMI
IPC: H01S5/14
Filed: 1985-02-07
Abstract: PURPOSE:To enable frequency modulation having a large frequency deviation by using a light source having high spectral purity by attaching an external resonator to a semiconductor laser and modulating frequency by utilizing the mode jumping of an external resonator mode by changing injection currents to the semiconductor laser. CONSTITUTION:Beams 2 projected from the rear end surface of a Fabry-Perot type semiconductor laser 1 are collimated by a lens 3, and fed back to the semiconductor laser 1 by a diffraction grating 4. Consequently, the simple substance of the semiconductor laser 1 multi-axial mode oscillates, but it single- axial mode oscillates by the wavelength selectivity of the diffraction grating 4, and sufficiently narrow spectral line width such as 100kHz is acquired. A DC bias circuit 5 is adjusted, and a bias level is set previously immediately before the semiconductor laser 1 mode-jumps at an external resonator mode. When a fine modulation signal is transmitted over the semiconductor laser 1 through a signal generator 6 and a driver 7, the semiconductor laser 1 repeats mode jumps in response to the modulation currents, and binary frequency modulation can be applied to output beams 8 from the semiconductor laser 1.
