Optoelectronic pressure sensor with Si.sub.3./sub.N.sub.4./sub. diaphragm
Beneš, P. ; Matějka, František ; Vrba, R. ; Kolařík, V.
Sensitive pressure sensor with nitride membrane and optoelectronic read-out system is described. Measured pressure is transformed into the deformation of a thick layer nitride membrane. Nitride membrane creates a mirror for laser beam and moves with reflected laser mark. Its position is sensed via a position sensing device - photo lateral diode. Diode double current signal is amplified and conditioned digitally by ADuC 812 microcomputer. This one chip provides an IEEE 1451.2 interface.

Autoemisní katody pro elektronové mikroskopy
Delong, Armin ; Kolařík, V.
Field emission emitters have significantly improved the coherence of electron guns in electron microscopes and allowed to reach atomic-scale resolution in the case of crystal imaging. Even now, thirty years after the first application of field emission emitters, one can hardly say that the development of electron emitters has been finalized
