Classification of photoelectric microscopes

Measurement Techniques Aims and scope

Conclusions

  1. 1.

    Photoelectric microscopes can be divided by the principle of their conversion into three groups, of amplitude, pulse-position, and modulated types. Each type has a characteristic functional circuit from which it is easy to determine the relationship between their measurement error and their circuit component parameters.

  2. 2.

    Pulsed PE microscopes are superior to others in their quality characteristics, such as stability of readings, range, etc.

  3. 3.

    The amplitude and modulated PE microscopes are mainly used as null detectors, whereas it is possible by means of pulsed PE microscopes to measure the position of graduation lines, as well as distances between them.

  4. 4.

    An analysis made by means of the information theory has shown that it is possible to evaluate the properties of photoelectric devices by means of information characteristics, such as the flow of useful information and the capacity of the reading unit. These characteristics are suitable for finding such parameters of microscopes as precision and speed of operation.

  5. 5.

    The above material is entirely suitable for analyzing various types of photoelectric coordinate-measuring devices.
