Title: Spatial wavefront evaluation by intensity relationship
Inventor: SIEBERT EDWARD T
IPC: G01J9/00
Filed: 1993-02-02
Abstract: SPATIAL WAVEFRONT EVALUATION   BY INTENSITY RELATIONSHIP          ABSTRACT OF THE DISCLOSURE            A  method,  and  apparatus  for  accomplishing  the method,  for determining a phase difference of a wavefront  at a  first  (pupil)  plane  (P1),  the wavefront propagating from the first plane to a second (image) plane (P2). The method includes the steps of providing an intensity of the wavefront at the first plane  measuring an intensity of  the wavefront at the second plane; and determining the phase difference of the wavefront at the  first plane in accordance with a transfer function that employs the provided intensity of the wavefront at the first plane and the measured intensity of the wavefront at the second plane. A single expression describing  an   Optical  Transfer   Function   is developed and is shown to involve only the unknown aperture phase and known quantities. A solution to this expression, achieved by a polynomial expansion technique or by a sampling technique, is shown to yield the phase at the aperture and, together with the  intensity  at  the  aperture,  to  define  the aperture wavefront.

Inventor: CARLE ARTHUR
IPC: A01M1/08
Filed: 1993-03-12
Abstract: The trap includes an enclosure from which it is possible to draw air therefrom thereby reducing pressure therein.   An opening is provided in the enclosure  which  enables  outside  air  to  be  drawn therein as a result of the reduced pressure,  and through which mosquitoes or night flying insects can be sucked inside the enclosure.
