Abstract: A specular array for radiometric calibration (SPARC) includes a plurality of spherical mirrors disposed upon a uniform background as at least one array of reflective points, at least two points reflecting a different intensity of directly incident sunlight. Each mirror has a radius of curvature and a diameter, the radius of curvature and the diameter providing a field of regard, the collective mirrors providing a collective minimum calibratability field of regard. Based upon the radius of curvature, the transmittance value of the sun to each mirror and from each mirror to a sensor being calibrated, the intensity of calibration light provided to the input aperture of a sensor to be calibrated within the collective minimum calibratability field of regard may be determined and used as a baseline for sensor calibration. An associated method of combined spatial and radiometric calibration is also provided.

Abstract: A goniophotometer includes two independent towers: a main support tower and an upright mirror tower. A swing arm is connected to the main support tower and can be rotated around a main horizontal axis. An elliptic flat rotation mirror, a first detector and a second detector are fixed to the swing arm. A test light source that is also connected to the main support tower can be rotated around a vertical axis. An upright round mirror is connected to the upright mirror tower. A far-field measurement can be achieved when a light beam from the test light source travels into the rotation mirror then is reflected to the upright mirror, and then is reflected by the upright mirror to the first detector. A near field measurement is achieved when the second detector receives a test light beam directly form the test light source.

Abstract: A gonioradiometric scanning apparatus and method for measuring the near and/or far field radiation pattern of radiating optical sources such as laser diodes (LD), light emitting diodes (LED), optical fibers, flat panel displays, and luminaires is described. The scanning apparatus incorporates a deflector for selecting an azimuth angle through the optical source to be measured, a rotating apparatus which collects light while scanning about the source, an optical commutator, and a detector. The rotating apparatus comprises a cylindrical hub and an optical collector using either an optical fiber or a train of reflectors, such as mirrors or retro-reflectors. The optical collector provides a means for both collecting light and for directing the beam emanating from the deflector to a place opposite the detector at which optical commutation occurs. The reflector optical train, when employed, folds the optical path and increases the effective radius of measurement, so that large radius scans can be obtained in an instrument with compact geometry. Depending on the source geometry and the effective optical path, the light collection can be either in the near field or the far field of the source radiation pattern. For the case of the far field radiation pattern, it will also be possible to measure the near field radiation patterns by imaging the source onto the light collection surface.
