PASSIVE MILLIMETER-WAVE IMAGING WITH EXTENDED DEPTH OF FIELD AND SPARSE DATA
... In this paper, we introduce a new millimeter wave imaging modality with extended depth-of-field that provides diffraction limited images based on a significant reduction in scan-time. The technique uses a cubic phase element in the pupil of the system and a nonlinear recovery algorithm to produce im ...

Light Polariser
... As with any form of energy, light can be produced in one place and have an effect in another place, which may be very distant from where it was produced. In this respect it is similar to a tennis ball that carries energy from the place where it is hit to the place where it lands. A sound wave also c ...

Consequences of the WFC3 IR detector 24 degrees tilt
... The current optical design for the IR channel of WFC3 has a focal plane tilted by 24 degrees to the chief ray due to the off-axis correcting optics. A similar design is used in, e.g., ACS but its effect is potentially amplified in WFC3 because of the bigger angle (it is only 11 degrees in ACS) and t ...
