摘要:
According to the present invention in the image forming light path a direction-selective diffraction element is provided in such a manner that the image forming beam having entered into said diffraction element is diffracted by means of the diffraction grating structure of said diffraction element and devided into a plurality of beams, whereby at least one of the diffracted beams is led to a photo detecting device while the not diffracted beam is made use of as the image forming beam.

Two-dimensional scanning apparatus scans a stationary two-dimensional surface with a first deflector and a second deflector which deflects a light beam in a direction perpendicular to the deflecting direction of said first deflector. An afocal optical system is provided between said first and second deflectors, while an imaging lens system is provided between said second deflector and the scanning surface. Said first deflector, afocal optical system and imaging lens system cooperate to displace the light beam at a constant speed in a principal scanning direction on the scanning surface, while said second deflector and imaging lens system cooperate to displace the light beam at a constant speed in an auxiliary scanning direction on said surface.

The disclosure describes a scanning optical system in which the scanning beam from a light source is deflected by a beam deflecting device to scan the scanning plane through a scanning beam focusing lens. The scanning optical system comprises a member disposed between the beam deflecting device and the focusing lens for reflecting a part of the scanning beam a plurality of times within the member so as to take up part of the beam as an information beam.

The present invention relates to a device for measuring light incident on an image forming optical system, making use of a plural number of the diffraction element. The plural number of the diffraction elements are respectively provided in the optical path of the image forming optical system. Further the plural number of the diffraction elements respectively present a certain predetermined area. The plural number of the diffraction elements, seen along the direction of the optical axis of the image forming optical system, are substantially only partially overlapped with respect to each other. The light beam incident on a diffraction element is divided into a non diffracted light beam and a diffracted light beam. Thus diffracted light beam is directed toward the light detecting means so as to be measured while the non diffracted light beam advances along the above mentioned optical axis. Consequently at the part at which the diffraction elements overlap each other, the non diffracted light beam led out of the preceeding diffraction element again enters the following diffraction element. This light beam is again divided into a non diffracted light beam and a diffracted light beam by means of the following diffraction element. The diffracted light beam is measured by a light detecting means in the same way as in the above mentioned case, while the non diffracted light beam advances along the above mentioned optical axis. Thus the light beam which passes through the overlapping parts is measured a plural number of times.

A color image carrier such as positive film is brought into contact with a monochrome recording medium such as silver salt film. The color image carrier is illuminated with red, green and blue beams. These three color beams respectively can project coded information about diffraction gratings or slits which are different in angle or pitch in accordance with the respective colors. Thus, each color image carrier containing the coded information about each diffraction grating or slit is recorded on the monochrome recording medium.

This invention relates to a sensing method and a sensing device for quantifying the concentration of an analyte by using the property that interaction between an analyte and a labeled compound changes fluorescence intensity. A fluorescence sensor is used to acquire fluorescence intensity at predetermined quantification time points. Then, the concentration of an analyte is quantified in accordance with a non-steady concentration quantification law comprising the relationship between the acquired fluorescence intensity and the time derivative quantity thereof.

According to a method of manufacturing a semiconductor device, a short-circuit wiring is formed in a region on a wafer including a dicing region, and electrode pads for input and output signals of a plurality of devices disposed in a semiconductor device forming region are electrically short-circuited by the short-circuit wiring, so that occurrence of plasma damage is suppressed even if the wafer is subjected to various plasma processes. When the wafer subjected to the plasma processes is cut along the dicing region to separate a semiconductor device, the electrical short-circuit of the electrode pads by the short-circuit wiring is released, so that the functionally unwanted short-circuit of the devices or the like is appropriately released.
