1. Optical measurement requires special attention to ensure a consistent linear calibrated response.2. The early studies were based on optical measurements only. 3. This has been enabled by the avoidance of modified nucleotides and optical measurements . 4. Optical measurement has been demonstrated on laboratory scale.5. Based on optical measurements , the object is between 300 and 800 meters in diameter. 6. The earliest such non-optical measurements were made of the thermal properties of the Sun. 7. The ACES experiment focused on the collection of electrical, magnetic and optical measurements of thunderstorms. 8. Ultimately, the effect of mandrel wrapping on optical measurements depends on the propagating mode power distribution. 9. Optical measurement avoids the need for Pitot tubes, hotwire anemometers or other intrusive Flow measurement probes.10. In 1941, he invented the Minnaert function, which is used in optical measurements of celestial bodies.
