| 1 | However, here again the angle of illumination is skewed. | |
| 2 | The polarization grade of three lamps for the laboratory and the polarization error of two illuminance meters are measured. | |
| 3 | The advanced backside illumination sensor captures great pictures even in low light. | |
| 4 | In intensity of illumination admirable by day, any colorific turns are flat and trenchant , proper. | |
| 5 | Photometry involves the measurement of luminous intensities of light sources and of the illumination of surfaces. |
