AN APPARATUS AND METHOD FOR MEASURING THE SPECTRAL PROPERTIES OF A FLUID |
| 摘要 |
<p>An apparatus and method for measuring the spectral properties of a paint, dye, enamel or other opaque fluid, both in transmission and reflection, wherein a lock-in amplifier (5) is used to increase substantially the signal-to-noise ratio of transmitted components of electromagnetic radiation passing through the fluid, thereby enabling transmittance measurements to be made to the order of 0.0001% or less of the incident electromagnetic radiation.</p> |
