ABSTRACT:
A method and system for testing the performance of at least one electro-optical test device, comprising constructing an electro-optical system having a light source, a test target, a lens and an imaging device as required in combination with the test devices. A respective identity code of a plurality of precalibrated devices together with corresponding electro-optical performances are stored in a database and the imaging device is aligned to the test target so as to produce a focused image thereof. Pre-calibbrated devices are selected from the database and the focussed image is digitized and stored so as to produce a digitized image which is analyzed so as to determine an electro-optical performance representative of the performance of the electro-optical system which is equal to the product of component electro-optical performances of each of the electro-optical test devices and each of the additional pre-calibrated devices. This permits determination of the product of component electro-optical performances of each of the electro-optical test devices.
