Optical sensor reflectance image

Measures in UV reflectivity mode are thus possible, using a 400 nm peaked narrowband filter. However, because of the glass optics absorption below 400 nm and the low sensor sensitivity in the UV, the quality of the images in UV reflection mode is not particularly good, because of the long exposure time need for compensating the low illumination on the sensor. [Pg.524]

Figure 8.1 Adaptive optics in astronomy, (a) The image of a star appears as a fuzzy blob in a telescope due to the wavefront aberrations caused by turbulence in the atmosphere, (b) If a deformable mirror is used to correct the image of the star to make it back into a point of Ught, a nearby galaxy with a more complex structure will also be corrected, (c) The wavefront distortions can be measured with a wavefront sensor. The wavefront distortions from the guide star are fed back through a control system to deform the adaptive mirror to a shape that is conjugate to the distorted wavefront, correcting the reflected wavefront of the guide star back into a plane wave.
