Researchers at Loyola Marymount University's (LMU) Center for Urban Resilience are using thermal imaging cameras from Flir Systems to better understand how hummingbirds can maintain strength with little rest. Thermal imaging helps unlock secrets of hummingbird energy usage. Courtesy of Flir Systems. Understanding the physiological mechanisms hummingbirds use to cope with extreme energy requirements and limitations may open the door to broader human medical applications such as the necessity to reduce oxygen and food consumption during long-term space travel.

Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market. While the 20th was the century of film cameras, the 21st belongs to the digital camera.The digital camera represents an integration of optics, mechanics and electronics consisting of three layers (Figures 1a, b and c).
