MEASUREMENT OF FORM OF SPHERICAL AND NEAR-SPHERICAL OPTICAL SURFACES

Rotational motions between a displacement-measuring probe and an optical test surface define a spherical or near spherical datum surface against which measurements of the probe are taken. The probe has a measurement axis that is maintained substantially normal to the optical test surface during the...

Zusammenfassung:	Rotational motions between a displacement-measuring probe and an optical test surface define a spherical or near spherical datum surface against which measurements of the probe are taken. The probe has a measurement axis that is maintained substantially normal to the optical test surface during the course of measurement. Des mouvements de rotation entre une sonde de mesure de déplacement et une surface test optique définissent une surface de référence sphérique ou presque sphérique contre laquelle des mesures de la sonde sont prises. La sonde présente un axe de mesure qui est maintenu essentiellement normal par rapport à la surface de test optique pendant le déroulement de la mesure.
