Title: Elektronenstrahlmessgerät
Inventor: PLIES ERICH DR RER NAT
IPC: G01Q60/00
Filed: 1989-06-19
Abstract: Konventionelle Strahlaustastsysteme sind in der Lage, Elektronenimpulse mit einer minimalen Breite von etwa 100 bis 200 ps zu erzeugen. Eine Verringerung der Impulsbreite auf einige 10 Pikosekunden ist zwar prinzipiell möglich, würde aber aufgrund der damit einhergehenden Verringerung des Sondenstromes zu einer erheblichen Verlängerung der Meßzeiten führen. Es wird deshalb vorgeschlagen, eine von einem gepulsten Laserstrahl (LA) beaufschlagte Photokathode (PK) zusätzlich an die Säule eines Elektronenstrahlmeßgerätes anzuflanschen und die Photoelektronenquelle mit Hilfe einer fokussierenden Ablenkeinheit (SFM) stigmatisch auf die Strahlachse (OA1) abzubilden. Als fokussierende Ablenkeinheit (SFM) kommt insbesondere ein Sektorfeldmagnet in Betracht.

Abstract: a method of detecting a wiring pattern using triangulation to detect a height thereof, comprising the steps of scanning a light beam (3) from a light source, illuminating the wiring pattern (2) to be detected by the scanned light beam (3), focusing the light reflected from the wiring pattern (2) or a substrate (1), applying the focused light beam to a beam-splitter (6) which splits it into a transmitted portion and a reflected portion, and converting a wiring pattern configuration to a corresponding electrical signal by monitoring the transmitted and reflected portions. By blurring the image of the focused light entering the beam-splitter or by having a blurred division in the beam splitter (6a) an extension in the measurable height domain of the wiring pattern is possible. Furthermore, by applying a correction factor in response to the height of the substrate, the detected output of the wiring pattern height for a curved substrate can be sliced with a more appropriate slice level.

In one mode the hand-held unit may be mounted in a fixed position in a terminal (11), in which case the data generated from the bar code reading operation is transferred immediately to the terminal and the reader is powered continuously from the terminal unit. In the other mode, the hand-held unit is separated from the terminal and held manually, in which case the data from bar code reading is stored in a local memory (31) to be later transferred to the terminal when the hand-held unit is again inserted into the terminal. A battery (23) in the hand-held unit is charged when the unit is mounted in the terminal, then powers the hand-held unit while operating remote from the terminal. The power for battery charging and the data transfer are accomplished without direct connections between the hand-held unit and the terminal.
