  1. Report on CIE Division 2CIE Session 2007 Beijing

  2. Contents • Introduction – Division 2 • Presented Papers • Technical Committee Meetings

  3. Introduction – Division 2

  4. What does Division 2 cover? • Measurement of Light and Radiation • UV, Visible and Infrared radiation • Optical properties of materials and luminaires • Optical properties and performance of physical detectors

  5. Who is Division 2? • Outgoing Director: Teresa Goodman (UK) • Incoming Director: Yoshi Ohno (USA) • Editor and Australian Representative: Jim Gardner

  6. Presented Papers

  7. Presented Papers • Papers presented at the conference include: • Absolute Integrating Sphere Photometry; • CCD-based Near-field Goniophotometry; • Characterisation of Integrating Spheres for accurate LED measurement;

  8. Presented Papers • Papers presented at the conference include: • Luminance contrast measurement of FPDs under daylight ambient condition; • Correction of stray light in CCD-based spectroradiometers and imaging devices; • Measurement of “naturalness”.

  9. Technical Committee Meetings

  10. TC2-40 • Standard for Characterizing the Performance of Illuminance Meters and Luminance Meters • New standard to give clear and unambiguous definitions for individual quality indices • Discussion surrounding characterisation of: • V () mis-match index f1’. • A new definition is likely to include uncertainty. • Directional response index f2. • Discussion regarding to measure out to 80° or 85° • The new definition will likely average the cosine response over four half-planes

  11. TC2-49 • Photometry of Flashing Lights • New technical report for photometric measurements of flashing light, including measurement of light sources, and calibration of photometers for flashing light. • New definition for derivation of “effective intensity” to replace the old B-R-D, Allard and Schmidt-Clausen.

  12. TC2-51 • Calibration, Characterization and Use of Array Spectroradiometers • Mainly for spectroradiometers that use CCD-arrays for real-time spectral measurement • Looking at properties of these devices, how to characterise and calibrate, and also sources of uncertainty • Subsequent meeting with TC chair in Melbourne

  13. TC2-59 • Characterisation of Imaging Luminance Measurement Devices (ILMDS) • Mainly for the devices that use CCD cameras to perform luminance measurements • Looking at properties how to characterise and calibrate, etc. • Scattered light, Linearity, Spectral Response, Uniformity, etc. • Binning, Blooming, Smear

  14. TC2-47 • Characterisation and Calibration Methods of UV Radiometers • Currently no uniform method of calibration that produces universally consistent results, ie: lamp and detector-dependant. • New guide will recommend methods for characterisation of UVA, UVB and UVC radiometers with quality indices similar to luxmeters.
