Title: Spectral diffraction method and device
Inventor: MACHIDA SUSUMU
IPC: G01N21/31
Filed: 1993-03-15
Abstract: PURPOSE:To make high sensitive measurements at a shot noise limit performable by detecting a transmitted light signal convergently detected after making the frequency modulated light signalincident in an interferometer with a balanced mixer, and suppressing an amplitude modulation element at the time of frequency modulation. CONSTITUTION:An inrush current 2 and an alternating current 3 are superposed with each other, and a laser illuminant 1 emits a frequency-modulated beam light. this beam light is halved at a branching beam splitter 10, and one side is reflected (12) after a spectral sample 4 is converted into FM to AM and vice versa. The other side is reflected (13) and then a phase shifter 14 varies its phase, and thereby both interferes with each other. Each output beam light of two interferometers is detected by two photodetectors 51 and 52, converting it into a detection current. This detection current is composed by a differential amplifier 9, while a frequency element alone of a modulatory alternating signal is measured by a frequency select detector 7, and an amplitude value is recorded (8). With this constitution, an undesired amplitude modulation element to be produced in time of converting the illuminant into the frequency modulation is fully suppressed, whereby it is operated less than the shot noise limit, thereby securing the high sensitive spectral diffraction.

Filed: 1985-03-20
Abstract: PURPOSE:To prevent the generation of cracks in a UV curing resin layer by providing an SiO film between a thin amorphous film consisting of a recording material which is a rare earth-transition metal and the UV curing resin layer. CONSTITUTION:An interference film 3 consisting of four kinds of SiO, ZnS, AlN and Si3N4, the thin amorphous film 4 and a protective film 5 are successively laminated by a sputtering method on the UV curing resin layer 2. The internal stress of the AlN and Si3N4 films is large and the resin layer 2 is cracked if the AlN and Si3N4 are used for the tilm 3. The extremely early decreased Kerr rotating angle is then resulted. The layer 2 is not cracked but the protective effect by the ZnS is not enough and the Kerr rotating angle decreases gradually if the ZnS is used for the film 3. The Kerr rotating angle does not change at all even after the lapse of a long period and the resin layer 2 is crack-free; in addition the stability of the SiO film itself is maintained if the SiO is used for the film 3.
