As a part of development of KOMPSAT3 Payload (Advanced Earth Imaging Sensor System) performed by Korea Aerospace Research Institute(under here KARI) this project is for a procurement of Large Integrating Sphere System which will be used for measurement of characteristics of payload such as signal to noise ratio linearity saturation and uniformity of radiometric response. The integrating sphere is the preferred tool for the measurement of radiant power or luminous flux of spot sources with a diverging light beam. Typical examples of spot sources are LEDs LED panels laser diodes fiber bundle light sources reflector spot lamps flat panel displays endoscopes and others. The reason why the integrating sphere is preferable to a planar detector is that typical photodiode detectors are limited in active area size and acceptance angle. Integrating spheres offer large area measurement apertures
and large acceptance angles in observance to the rule that the ‘measurement aperture area should not exceed 5% of the total sp |
