Abstract
Method and apparatus for recording and/or indicating a function of two variables, characterized in that a signal having a value Z which is a function of two variables X and Y is quantified and is then represented in quantified form. The representation in quantified form is effected by projecting a luminous spot on a display area at the point of coordinates (X, Y) wherein the luminosity of the spot represents the quantified form of the value Z.
Claims27
A method for at least indicating a function Z of two variables X and Y comprising the steps of quantifying the value of the function Z and displaying the quantified form of the value of the function Z by projecting a luminous spot on a display area at the point of coordinates (X, Y) and providing a luminosity for the spot representative of the quantified form of the value of the function Z.
Apparatus for at least indicating a function Z of two variables X and Y comprising quantifying means for receiving a signal representative of the function Z and providing a quantified function Z output signal, and means for displaying the quantified function output signal including means for projecting a luminous spot on a display area at the point of coordinates (X, Y) and providing a luminosity representative of the quantified function signal.
