Automatic non-contact measuring optical properties of an optical object is performed by a system comprising a light source, a reference pattern, and an imaging and detecting means and an image processing means for producing a measurement output. At least the reference pattern and the imaging and detecting means are disposed on an optical axis of the system, The system further comprises a support for the optical object located between the reference pattern and the imaging and detecting means for disposing thereon the optical object coaxially with the pattern and the imaging and detecting means. The light source is capable of directing to the pattern an illuminating light in such a manner as to produce a plurality of illuminating light beams outcoming from each point of the pattern at different angles. The imaging and detecting means is capable of obtaining an image of the pattern through the optical object so that each imaging beam is conjugate with only one of the illuminating beams, and of recording the image for its processing by the image processing means.
