Abstract More effective methods for counting greater sage-grouse (Centrocercus urophasianus) are needed to better assess population trends through enumeration or location of new leks. We describe an aerial infrared technique for conducting sage-grouse lek counts and compare this method with conventional ground-based lek count methods. During the breeding period in 2010 and 2011, we surveyed leks from fixed-winged aircraft using cryogenically cooled mid-wave infrared cameras and surveyed the same leks on the same day from the ground following a standard lek count protocol. We did not detect significant differences in lek counts between surveying techniques. These findings suggest that using a cryogenically cooled mid-wave infrared camera from an aerial platform to conduct lek surveys is an effective alternative technique to conventional ground-based methods, but further research is needed. We discuss multiple advantages to aerial infrared surveys, including counting in remote areas, representing greater spatial variation, and increasing the number of counted leks per season. Aerial infrared lek counts may be a valuable wildlife management tool that releases time and resources for other conservation efforts. Opportunities exist for wildlife professionals to refine and apply aerial infrared techniques to wildlife monitoring programs because of the increasing reliability and affordability of this technology.

Nowadays, porcelain string insulators are commonly used in high voltage transmission lines. The study of temperature distribution is extensively performed in the design and development of high voltage insulations. As known, the infrared technology has opened the door to a variety of applications and especially it is also used as a kind of non-contact remote detection technology which has the advantage for detecting high voltage faulty porcelain insulator. Thanks to it, this paper uses the infrared technology to investigate the temperature distribution of the 220kV power grid insulator string. The experiments were done in climate chamber to study. Firstly, determining the thermal stability time of the high voltage porcelain insulator called XP-70 type composing of 14 pieces under the tested voltage of 127kV based on the temperature and voltage distribution. And then the temperature distribution along the normal and fault insulator string experiments. The experimental results show that it may detect and compare the insulator metal cap temperature of faulty insulator in the porcelain insulator string and determine the location of them. And especially based on the unchangeable voltage distribution, it may detect the temperature distribution characteristic for the fault insulator string. Therefore, this research results can provide a reference to detect the faulty porcelain insulator strings
