A new method of fabricating refractive microlens by melting photoresist was presented in this paper. The microlens array composed of 20 × 20 F/2 microlens with 90 μm diameter on 100 μm centers have been obtained. The wave aberration of the microlens was estimated less than 1.3 wavelength.
In this paper we describe a treatment of calculating the wave front abrration with respect to an astigmatic reference surface according to Michael P.Chrisp's wave aberration theory of plane symmetric grating system the present the obtained spot diagrams on the last image surface and show the calculation programs.
Study on accuracy and repeatability of measuring wave aberration of human eye with Hartmann sensor is carried out. Defocusing accuracy for measuring human eye is 0.2D and average error of wave aberration is 65nm.
Based on the wave aberration theory,the relation between wave surface variance and the number of subapertures is derived when some aberration exists in single subaperture of the optical synthetic aperture imaging system.
A three-mirror,unobscured,high-resolution optical system with large aperture,long focal length was aligned and the results of 0° field wavefront error of 0.094λ rms,+1° field of 0.106λ rms and -1° field of 0.125λ rms at λ=632.8 nm are obtained.
To characterize the optical performance of the eye the deviation of the wavefront of a foveal image point from its ideal (spherical) shape (wavefront aberration) was determined.
The wavefront aberration is represented mathematically in Zernike polynomials.
However, the drastic changes of beam spot, beam intensity profile, modulation transfer function curve and wavefront aberration were not observed.
Using zoom optics, an additional aspheric lens surface, and a diffractive optical element together, the wavefront aberration and chromatic aberration are effectively reduced in a broad range of cover-layer thicknesses and wavelength variations.
