Comparative analysis of the DFB fiber laser and fiber-optic interferometric strain sensors [PDF]

, 2007
The DFB fiber laser strain sensor is shown to provide an improvement in the minimum detectable length change by a factor of 275 at 2 kHz for an applied strain when compared with an interferometric sensor interrogated by at equivalent DFB laser.

Potassium Application Increases Cotton (Gossypium hirsutum L.) Fiber Length by Improving K⁺/Na⁺ Homeostasis and Potassium Transport Capacity in the Boll-Leaf System under Moderate Salinity

Agronomy, 2022
Cotton has a high salt tolerance. However, due to the high salt content and low K+/Na+ ratio in saline soils, cotton yield and fiber quality are difficult to improve. To investigate the effects of potassium (K) on cotton fiber length under salt stress, a
