WebFig. 3. Grating is illuminated with a heating beam whose power can be varied using a wave plate and a polarizer. The surface dis- tortions are probed using a helium–neon laser and a Shack– Hartmann wavefront sensor. The probe beam is incident at 30° to the grating surface normal. Fig. 6. WebUnder this Phase II SBIR effort Kestrel Corporation proposes to demonstrate the advantages of a distorted grating based wavefront sensor for measuring wavefront aberrations under propagation conditions that simulate the high levels of aberrations found inan Airborne Laser (ABL) application. WebHowever, occasionally the view looks a little off. It might be warped or wavy. If it is, that’s an example of glass distortion. Glass gets distorted in a few different ways, most of which … bot fly infestation
