Abstract: A prober for measuring the light output of digital devices integrally formed on a single wafer. The prober includes a light-integrating sphere sequentially aligned with selected devices. Each time that a device is aligned with the sphere, the device aligned with the sphere is activated, so that the light output of each device is individually measured. In the disclosed embodiment, the devices are vertical cavity surface emitting lasers (VCSELs) and light emitting diodes (LEDs).

Abstract: Apparatus for measuring the radiation power of lasers, particularly infrared lasers, with a thermal detector, which supplies a power-caused measurement signal.In order to be able to measure rapid laser radiation power changes, the apparatus is so constructed that there is a device which locally integrates the laser radiation and to which, apart from the thermal detector, is connected at least one further detector, which is able to detect radiation power changes with a larger band width than the band width detectable by the thermal detector and that there is a circuit combining the measurement signals of the detectors.

Abstract: A method and apparatus for measuring low-level laser-induced fluorescence are disclosed. A laser is used to produce a coherent beam of light which is sequentially passed through a beam expander, iris diaphram, focusing lens and three-dimensional scanner before being focused onto a rigidly mounted target. A computer is used to predeterminately control the pattern and the rate at which the scanner passes the beam of light over the target. The light transmitted onto the target induces fluorescent light in the target. The fluorescent light is sequentially gathered by a biased cut optical fiber member and directed into a photomultiplier tube where the intensity of the fluorescent light is measured. The intensity data is then digitized and recorded by the computer as a function of the coordinates of each preprogrammed point location of the beam impinging upon the target. This data is used to produce an image of all or a portion of the target on a visual monitor. In addition, the data can be recalled and used for further analysis of the target.
