Abstract:
The diffraction effects in exploring plasma and shock wave produced by high-power laser by opt ical non-contacting methods were studied. The diffraction theory and imaging theory of lens were used. A new method was presented: When the receiving element makes a conjugate body-image relationship with the measuring region, the error caused by diffract ion effects in measuring the plasma and shock wave can be overcome obviously. The conclusion is deduced in theory. The feasibility is verified by combining the experimental results.
