    摘要： A fringe deflectometry apparatus illuminates an optical component to be measured using radiation with a known wavefront, deflects the radiation after it has been reflected or transmitted by the optical component to be measured, and materializes a reference ray. Transverse aberration of the reference ray after reflection or transmission by the optical component is measured. A deflectometry method using the apparatus enables an absolute phase reference to be provided.

    摘要： A device for phase detection testing any kind of optical system, in particular an ophthalmic lens, comprises, along an optical path, an emission device which constitutes a light source, a holding station which receives the optical system under test, an array, a receiving device which receives the image observable downstream of the array, and a data processing device which exploits this image by phase detection. Between the light source and the holding station is a separator element which constitutes on the axis of the optical path a semi-reflecting surface. The receiving device is disposed to the side, in line with the separator element. The data processing device includes a ray plotting program and a calibration system allowing for theoretical and manufacturing aberrations due to the separator element.

    摘要： A method and device for measurement of the geometrical or optical structure of an optical component such as a lens or a mold for making lens are provided. The method comprises the steps of illuminating the optical component to be measured with incident light having a known wavefront, measuring, in a given plane, the maps of the wavefront slopes of the light, after reflection at or transmission by the optical component, and deducing the surface topography or refraction index map of the optical component to be measured from the measurements of the slope maps by the application of at least one calculating procedure.The calculating procedure comprises a step in which a result surface is initialized using a simple starting surface SD' and at least one optimization step; each optimization step involves calculation of the value of a merit function representative of the departure between the result surface and the surface to be measured of the optical component and, minimization of said value varying said result surface, said variation being expressed in the form of at least one intermediate surface S.sub.i.

    摘要： A system for measuring a solution pH includes a potentiostat with a working electrode made of an electro-conductive solid polymer transducer, an input to receive the potential to be applied between the working electrode and a reference electrode, and an output to transmit a signal representative of the current flowing between a counter electrode and the working electrode, the three electrodes being immerged into the solution. The system further includes a digital processor connected to a digital to analog converter for generating the potential to be applied between the working and the reference electrodes; and to an analog to digital converter for receiving a digital value representative of the current. The digital processor is adapted to modify the potential to maintain the current inside a predetermined range such that the potential is representative of the solution pH when the current is inside the predetermined range.
