METHOD OF NESSBAUER SPECTROMETER CALIBRATION

One of the interference beams, formed after splitting of the beam of laser (4) in an optical block (5), is directed into the movable arm and is passed repeatedly between movable and fixed reflecting elements (6,7). The output beam is then summed with the second beam and photo-detector (8) is adjuste...

Beschreibung
Zusammenfassung:	One of the interference beams, formed after splitting of the beam of laser (4) in an optical block (5), is directed into the movable arm and is passed repeatedly between movable and fixed reflecting elements (6,7). The output beam is then summed with the second beam and photo-detector (8) is adjusted to max. illumination of the central spot. Time mark generator (1) then forms two pulse trains which pass to a counter (10) and control device (2) of a Doppler modulator (3), with a speed sensor in its correction feedback. During movement of the movable section of the modulator (3), a photo-detector registers the modulated light flow and passes an electric signal via an amplifier-shaper (9) to a memory register (11) a control circuit (12) synchronises recording of codes from a counter (10) and memory (11) in a recording device (13). After an assigned number of cycles an electronic computer (14) calculates variation of speed in each channel and the parameteres of the Mossbauer spectrum. - (First major country equivalent to CS8607338) (7pp Dwg.No.1/1)
