INTRODUCTION

• VISpION is a fractal-structured optical sensor system that uses a new algorithm for

the analysis of materials or processes. Because of this, it offers many important

advantages over traditional optical imagery.

• VISpION is especially useful in amorphous or difficult-to-interpret applications

where subtlety, apparent chaos, disturbing environmental factors, or ambivalence

can confuse other sensor systems or cause them to fail.


• VISpION does not have to take the time, nor to demand processing overhead, to

construct a pixelized image and to engage in pixel analysis.

• VISpION may operate with visual light, or with a more limited light spectrum, orwith infra-red, ultra-violet, with acoustic wavelength, magnetic wavelength, with

hologram, etc.

The illumination may be reflected or transmitted through the object(s) or process.

In some applications, even ambient light will provide sufficient illumination.

COMPETITVE ADVANTAGES

VISpION fractal analysis offers:

• the ability to analyse the in real time with no upper limit on the speed of analysis

• abstraction of data from extremely ambiguous or difficult-to-read objects orprocesses

• excellent performance in harsh environments

• a much reduced digital overhead

• extremely fine resolution from microscopic to macroscopic

• exponentially improved ratio of cost to value compared to traditional optical sensors

• easy to use in a wide range of applications and industries with maximum flexibility in thechoice of optical or electro-magnetic front end


HOW IT WORKS

The principle:

VISpION is designed to recognize certain patterns in specimens and processes.

These patterns are created by: surface texture, shape, color, gloss, opacity,

consistency of features, resolution, plasticity, elasticity, surface tension, etc.

VISpION then calculates a fractal component, a real number, to represent any

selected criterion, or group of criteria. The fractal dimension is then compared to

previously calculated tolerance parameters.


HOW IT WORKS


1 Object to be examined

The object is illuminated to reveal the critical characteristics

2 Vispion- signal generationScaling geometry is applied using at least two channels (three shown here: a,b,c)

each employing a different sized field of the object characteristics

3 Extract filterStandardization of the channels and determination of structure code

4 Box- Operation Calculation using the VISpION fractal algorithm to interpret the structure code as a single

real number

5 Numeric structure code Numerical comparison to base-line quality control parameters

HOW IT WORKS > SAMPLE CONFIGURATION 1


In this example, different sized, but geometrically similar receptors on the receiver (photo

converter), match the shape and area of the scanned areas on the object surface, as

transmitted by the optics, except for distortions as a result of surface topography.

The functional principle of the VISpION sensor lies in the operation of two or more modules

that create similar signals and perform a mapping function that is varied by scaling

instructions. The following examples illustrate just a few of the unlimited applications of the

VISpION sensor system.



In this example, an object which is transparent in part, with inlayed and attached characteristics,

passes through the sensor. Each of two receivers create separate signals based on a fractal

interpretation of contrasting characteristics of the surface as revealed by the light transmitted through

the object.

Two areas of light reception, each the same shape and size, receive illumination in two differently-sized

areas.

A movement of the object typically results in gradients of brightness within the areas of scanner

inspection.



This example shows an anisotropic bar pattern on the specimen, with light reflection interpreted in

binary fashion. The creation of the signal takes place with only one converter. Adequate contrast is

created even in diffuse reflected light.

The size of the scanned area A is defined by the active area of the converter within the receiver. The

acitve exposure is alternately increased to accommodate scanning area B. In addition, the occurance

of scanned area B is a function of the speed of object movement.

The scanned areas have the same width, but specifically different lengths (a function of exposure and

velocity) such that for example scanned areas A and B, B/A = 2.

Sample B

1 Engine Block Castings


VISpION examines engine block castings for Daimler AG.


2 Combustion Analysis

The VISpION receiver unit can also be modified to conform geometrically to the

shape and appearance of examined objects, objects flows, or processes.

The system can demonstrate continued “learned” refinement of fractal geometry.

This capability permits extremely economical and instant analysis of inconsistent

processes, not possible optically, and is thus ideal, for example, for monitoring the

development and flow of a combustion process.


The system analyses the wavelength, and thereby the temperature, and also the

continuity of a flame process.
