To propose an ultrasonic exploration method and an ultrasonic exploration apparatus that allow exploration of an exploration-target area such as a welded portion to provide a cross-sectional image of the exploration-target area accurately and stably.

[Solution] An exploration operation, in which the transmission/reception position, at which ultrasonic waves are transmitted and received, is changed by a specified pitch distance, is performed for each of a plurality of incident angles. A nonlinear image in which echo signals acquired from harmonic waves of reflected waves are presented is generated for each incident angle.

Frame conversion images formed by only echo signals 41a whose signal intensity is the signal intensity threshold or more are overlapped to generate a nonlinear exploration image 35. Exploration of a welded portion 23 stably provides a nonlinear exploration image 35 in which the shape of an interface 25 of the welded portion 23 is shown accurately and clearly.

In a method for improving the imaging properties of a projection objective of a microlithographic projection exposure apparatus, an appropriate illumination angle distribution adapted to a mask (24; 224) to be projected is selected. Then locations (40a, 40b; 60a, 60b; 80a, 80b, 80c) in an exit pupil of the projection objective (20), which are illuminated under these conditions by projection light during a projection of the mask, are determined. For at least one image point, an actual value of an imaging quantity, e.g. a wavefront profile or a polarization state, is determined that influences the imaging properties of the projection objective. Finally, corrective measures are calculated such that the actual value of the imaging quantity approximates a desired value at these locations. In this last step, however, deviations of the actual value from the desired value are taken into account exclusively at said locations illuminated in the exit pupil.
