Abstract: A radiance source (20) includes a housing (40) having an interior wall (42), wherein at least a spherical portion of the interior wall (42) of the housing (40) is spherical, an interior volume (46) and an exit port (48). A light source (82) is disposed within the interior volume (46) of the housing (40). A calibration structure (84) blocks and reflects a light ray that would otherwise travel directly from the light source (82) to the exit port (48) without reflecting from the interior wall (42). The calibration structure (84) has a calibration body (86) having a curved back surface (88) facing the light source (82) and a curved front surface (90) facing the exit port (48). There is an optically diffuse, lambertian reflecting surface (96) on at least the spherical portion of the interior wall (42) of the housing (40), the back surface (88) of the calibration body (86), and the front surface (90) of the calibration body (86).

Abstract: An optical position tracking system that tracks the position of objects, using light intensity and/or frequency with the application of geometry and ratios of detector responses, is provided, having light distributing and light detecting components (59) that employ the concepts of constructive occlusion and diffuse reflection. Diffusely reflective cavities (16), masks (M) and baffles (51) are used to improve certain radiating characteristics of the distributing components (59) and certain response characteristics of the detecting components (59), to tailor the radiation and detection profiles thereof, including them substantially uniform for all angles within a hemispheric area which the distributing and detecting components (59) face. The distributing and/or detecting components (59) are partitioned with specially configured baffles (51). A partitioned distributor has distinct emission sections where the sections can emit spectrally-different or distinguishable radiation. A partitioned detector has distinct detection sections where the sections can detect radiation from different directions.

Abstract: Verfahren zur Bestimmung der Strahlungswellenlänge und der wellenlängenkorrigierten Strahlungsleistung monochromatischer Lichtquellen, sowie Einrichtung zur Durchführung des Verfahrens.
Es wird ein schnelles und unaufwendiges optoelektronisches Meßverfahren zur Bestimmung der Wellenlänge und der wellenlängenkorrigierten Leistung monochromatischer Lichtquellen angegeben. Die Photodetektoren (1, 2) unterschiedlicher spektraler Gesamtempfindlichkeit werden mittels einer Beaufschlagungsvorrichtung (B) mit dem Strahlungsfluß der zu messenden Lichtquelle beaufschlagt und die dabei entstehenden Signale (11, 12) über eine Meßwerterfassungs- und verarbeitungseinheit (3) der Recheneinheit (4) zugeführt. Aus den Signalen (11,12) wird in (4) eine wellenlängenspezifische Größe abgeleitet, die mit den in der Speichereinheit (6) nach einer einmaligen Kalibrierung vorhandenen wellenlängenspezifischen Daten verglichen wird. Dadurch kann die aktuelle Wellenlänge der zu messenden Lichtquelle bestimmt, mit einer Anzeigeeinheit (7) angezeigt oder mit einer Datenschnittstelle ausgegeben werden. Mit Kenntnis der aktuellen Wellenlänge kann in (6) ein wellenlängenspezifischer Korrekturfaktor abgefragt und in (4) eine wellenlängenkorrigierte Leistung errechnet werden. Zur Beaufschlagung der Photodetektoren (1, 2) können Strahlungsteiler. Lichtwellenleiter mit entsprechenden Verbindungsstücken oder Ulbricht-Kugeln dienen.
