These aberrations take a number of forms. First there are changes in the image with the color. These are referred to as chromatic aberrations. Then there are a subset of aberrations that are called monochromatic aberrations. One type of monochromatic aberration is a failure to get a point image of a point object.

WebJul 29, 2012 · Presentation Transcript. Chromosomal Aberrations • Can be caused either by • non-disjunction (failure of whole chromosomes to separate during meiosis) • translocation (bits of chromosomes that are re-attached to other chromosomes). Individuals end up either with extra whole or bits of chromosomes or with missingwhole or bits of chromosomes. WebThe aberrations and properties corresponding to these Zernike terms are shown in Table IV. Writing the wavefront expansion in terms of field-independent wavefront aberration coefficients, we obtain (58) Because there is no field dependence in these terms, they are not true Seidel aberrations. Wavefront measurement using an interferometer only ...
WebAn optical aberration is a property of an optical system that causes the light that goes through it to spread rather than to focus on a point. In other words, aberrations are imperfections of optical systems. They are not caused by defects in the making of devices but rather because of their physical conditions.
