In the first part of this paper, we examine previously used methods for the assessment of the subjective performance of lenses coupled to the eye, we establish the need for a unified means of assessment in terms of visual tasks and targets, and we propose such a means. In the second part, we address some common aberration balancing questions, with a view to presenting concrete recommendations for optical design. The balancing questions examined are: defocus and accommodation, accommodation and longitudinal color, spherical aberration and defocus, astigmatism and field curvature, field curvature and accommodation, transverse color and astigmatism, and coma and astigmatism.
A new type of laser generating nanosecond and picosecond pulses is presented. Pulses of 20ps and about 10mJ can be generated. The advantages of the proposed mode locking method are the enhancement of reproducibility ( about 100% ) and reduction of time jitter to nanoseconds, also large mode volume and high beam quality can be obtained by proper coupling of the two cavities.
