Abstract:
The invention relates to an in-line optical method of inspecting transparent or translucent objects (2) running at high speed between a light source (3) and means (4) for taking images of the objects and for analyzing the images taken, so as to detect defects in the objects. According to the invention the method consists: in controlling the single light source (3) so that said source produces in succession two types of illumination for each object running past said source, the first type being a homogenous illumination whereas the second type is formed from alternate dark zones and light zones with a discontinuous spatial variation; in taking images of each running object when each of them is illuminated in succession by the two types of illumination; and in analyzing the images taken with the illuminations of the first and second types for the purpose of detecting high-contrast defects and low-contrast defects respectively.

Abstract:
The compact microspectrometer for fluid media has, in a fixed spatial coordination in a housing, a light source, a fluid channel, a reflective diffraction grating, and a detector. The optical measuring path starting from the light source passes through the fluid channel and impinges on the diffraction grating. The spectral light components reflected by the diffraction grating impinge on the detector.
Abstract:
PROBLEM TO BE SOLVED: To provide a sensor of a remarkably reduced cost and size, requiring no secondary attachment and no positional alignment. SOLUTION: This sensor 30 is a sensor such as a lateral flow sensor including a chemical layer 32 and a detector 36 on a flexible substrate 40. An optical signal is generated in response to an analyte 34 arranged on the chemical layer. The presence or absence and a concentration of the analyte are detected by detecting the optical signal by the detector. The detector is mounted on the substrate. The chemical layer and the substrate are layered each other to form the integrated sensor. The sensor may include a light source 42. The light source may be arranged on the substrate, or on a side opposite to the detector in the chemical layer. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a PCR (polymerase chain reaction) equipment being an optical equipment for quantitative monitoring of replicative DNA which is improved in a dynamic range, capable of automatically selecting the exposure time for expanding a dynamic range, capable of automatic drift adjustment, easy to operate, relatively low price, and easy to change the optical system for storing a different fluorescence dye. SOLUTION: The equipment includes a light source, a light guide means for guiding a light beam, an optical detector, and a means for processing a data signal. The light source emits source beam containing at least one frequency of primary excitation frequency capable of making fluorescence emit with emission frequency. A 1st means is so arranged as to activate an excitation beam of excitation frequency while receiving the source beam. A 1st focus means is arranged to focus the excitation beam in each suspension to make the primary dye emit emission beams with intensity indicating the emission frequency and the DNA concentration of each suspension. A focus means receives an emission beam and makes it pass through. A 2nd means is arranged to receive the emission beam to pass through the emission beam of emission frequency to the other focus means which focuses the emission beam on the detector. The detector generates a primary data signal representing the emission beam and generates the concentration corresponding to the DNA of each small bottle. The processor displays the concentration of DNA by acquiring the primary data signal. COPYRIGHT: (C)2006,JPO&NCIPI
