Visible and invisible mirages: comparing inferior mirages in the visible and thermal infrared.
نویسندگان
چکیده
Visible (VIS)-light and thermal infrared (IR) inferior mirages in the 8-14 μm waveband have been observed simultaneously for the takeoff and landing of various airplanes at distances of several kilometers. Similarities as well as differences between the VIS and IR mirages are discussed.

Aquarium, Computer, and Alaska Range Mirages
F my house in Fairbanks, Alaska, I see Mt. McKinley 250 km to the southwest. One hundred fifty kilometers to the south is Mt. Hayes, and 200 km to the southeast is Mt. Hadjukovich. But in the winter it is often hard to know what these Alaska Range mountains really look like. They appear as mirages, distorted into towering images, squashed images, inverted images, or floating images (see Figs. 1...
متن کاملFusion of Thermal Infrared and Visible Images Based on Multi-scale Transform and Sparse Representation
Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...
متن کاملDistributed Ray Tracing of Mirages
To further increase the realism of ray tracing, we take the idea of distributed ray tracing and add on to it mirage rendering. Mirages are seen quite often in our daily lives, and in order to make computer generated images look as realistic as possible, it is necessary to add things, such as mirage rendering, that are seen in the natural world. Mirages are caused by light passing from colder ai...
متن کاملObservational Features of Black Holes
Recently Holz & Wheeler [59] considered a very attracting possibility to detect retro-MACHOs, i.e. retroimages of the Sun by a Schwarzschild black hole. In this paper we discuss glories (mirages) formed near rapidly rotating Kerr black hole horizons and propose a procedure to measure masses and rotation parameters analyzing these forms of mirages. In some sense that is a manifestation of gravit...
متن کاملInvisible Phenomena in the Overall Personality of Man, in the Interpretive Study of the Verses 38 and 39 of Haqqah
There is a visible and invisible element in all creatures. There are also realities in human beings, some of which are visible and most of which are invisible. The preference of the invisible is not limitted only to quantities but includes qualitaties also. This division is inspired by the verses 38 and 39 of Haqqah: Most commentators of the Holy Qur'an believe that the external instances of th...
