    摘要: A signal power control device comprises two amplification channels. A first amplification channel comprises a first transconductance amplifier and a second amplification channel comprises an attenuator mounted in series with a second transconductance amplifier. Gain adjustment means allow the respective gains of the first and the second amplifier to be controlled independently, according to laws, ensuring optimum output dynamics across the entire gain range of the power control device.

    摘要: The collimated test object according to the invention is used for projecting to infinity a set of marks, the positions of which are very accurately known so as to be able to verify the alignment and/or the distortion of optical equipment such as sensors or collimated screens. This test object comprises a plurality of microcollimated sets, each comprising a light source, an elementary test object comprising a mark illuminated by the source as well as a collimation lens for projecting the mark to infinity. With this solution, one gets free of aberration problems to which are subject convention test objects of large dimensions.
