Rayleigh Criterion

12 Followers

• Diffraction limits resolution. • For a circular aperture, lens, or mirror, the Rayleigh criterion states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other. • This occurs for two point objects separated by the angle θ = 1.22 λ / D, where λ is the wavelength of light (or other electromagnetic radiation) and D is the diameter of the aperture, lens, mirror, etc. This equation also gives the angular spreading of a source of light having a diameter D. From http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/Raylei.html Average vision is 5 × 10⁻⁴ radians or 103.13 arcseconds or a ratio of 1:2000 [1 unit resolvable at 2000 units]

Philosophy has always been a search for spiritual truth, a process of going more deeply into the knowledge of nature, the human being and the universe. Every act of searching is at the same time an exercise of freedom of consciousness in opposition to ignorance, confusion and the prejudices that prevent calm and deep reflection. For us, Philosophy is an innate attitude in human beings. Our task is to enable that innate attitude to be expressed in actions that will allow us to develop our full potential and improve our world. We propose a practical philosophy that will be useful for each individual and for society. We do this not only through reading, studying and theoretical knowledge, but also by setting ourselves the goal of learning to live well, with strength and efficiency, at every moment in our lives; taking advantage of the opportunities that arise and learning something positive even from adversity. This is what we mean by «Philosophy as a way of life».

Contribua com nosso canal através do PIX oratiobyromariommatias@gmail.com O canal de opiniões, lugar de fala e a preservação da liberdade dela. Oratio, que vem do latim, como um "lugar de fala". Também pode ser definido como "o racional", que também deriva do latim, já que o lugar aqui é de expressar o pensamento com lugar de fala O que me faz estar motivado com esse canal é o movimento recém ocorrido sobre a tentativa de calar a liberdade no país. O PL 2630 vindo do Partido C0MUN15TA do Brasil é o autor, e podemos ser vozes para não permitir tal feito premeditado e muito mais.
