Abstract: | In astronomical observation, it is difficult to obtain the image of faint objects in the peripheral area around a bright celestial
body. In order to solve the problem, a new method is designed and experimented, which is called the separation readout technique
(SRT). SRT is different from either the traditional coronagraphy or the newly-developed anti-blooming CCD technique, and allows
an enough-long exposure to the faint objects in the area around a bright celestial body with the well-preserved bright body’s
image in one frame. This paper describes in detail the principle of SRT, the computer simulation, the experimental devising
and result of SRT observation on a telescope. |
