Description
Sistema óptico para la acromatización del ojo humano.Optical system for eye acromatization human.
Se trata de un doblete óptico pegado, compuesto por una lente simple de vidrio, o de material polímero, en la que, en una de sus superficies, se ha tallado una lente difractiva, formando así el doblete. Este sistema acoplado al ojo humano corrige su aberración cromática axial, minimizando las aberraciones oculares residuales.It is a glued optical doublet, composed by a simple lens of glass, or polymer material, in which, on one of its surfaces, a diffractive lens has been carved, thus forming the double. This system coupled to the human eye corrects its axial chromatic aberration, minimizing aberrations residual eyepieces
Desde que se evaluó con precisión la aberración cromática axial del ojo humano, se ha especulado sobre su influencia en la calidad visual de nuestro ojo. Así se diseñaron sistemas compuestos formados por elementos ópticos convencionales (lentes refractivas), básicamente dobletes [Bedford, R.E., Wyszecki, G., axial chromatic aberration of the human eye, J. Opt. Soc Am., 1957, Vol. 47, pp. 564-565], tripletes [Bedford, R.E., Wyszecki, G., axial chromatic aberration of the human eye, J. Opt. Soc Am., 1957, Vol. 47, pp. 564-565, Lewis, A.L., Katz, M., Oehrlein, C., A modified achromatizing lens, Am, J. Optom. Physiol. Opt., 1982, Vol. 59, pp. 909-911] y combinaciones de un doblete y un triplete [Powell, I., Lenses for correcting chromatic aberration of the eye, Appl. Opt., 1982, Vol. 20, pp. 4152-4155], que han corregido con éxito la aberración cromática axial del ojo, para evaluar la influencia de ésta sobre la calidad de imagen visual de nuestro ojo. Sin embargo, con la mejora hoy día de los métodos de fabricación de elementos ópticos difractivos puede compactarse aún más el sistema, reduciendo el peso y costo.Since aberration was accurately evaluated axial color of the human eye, has been speculated on its influence on the visual quality of our eye. So they were designed composite systems formed by conventional optical elements (refractive lenses), basically doublets [Bedford, R.E., Wyszecki, G., axial chromatic aberration of the human eye, J. Opt. Soc Am., 1957, Vol. 47, pp. 564-565], triplets [Bedford, R.E., Wyszecki, G., axial chromatic aberration of the human eye, J. Opt. Soc Am., 1957, Vol. 47, pp. 564-565, Lewis, A.L., Katz, M., Oehrlein, C., A modified achromatizing lens, Am, J. Optom. Physiol Opt., 1982, Vol. 59, pp. 909-911] and combinations of a double and a triplet [Powell, I., Lenses for correcting chromatic aberration of the eye, Appl. Opt., 1982, Vol. 20, pp. 4152-4155], which have successfully corrected the axial chromatic aberration of the eye, to assess the influence of this about the quality of visual image of our eye. But nevertheless, with the improvement today of element manufacturing methods diffractive optics can further compact the system, reducing The weight and cost.
Diseño de un doblete híbrido, formado por una lente refractiva y una difractiva, pegadas, cuya potencia en función de la longitud de onda compensa a la que posee el ojo humano, con lo que, acoplado dicho doblete al ojo, forma un sistema libre de aberración cromática axial.Design of a hybrid doublet, formed by a refractive and a diffractive lens, glued, whose power in wavelength function compensates for the eye's human, with which, coupled said doublet to the eye, it forms a system free of axial chromatic aberration.
- La invención consiste en un sistema formado por una lente simple de un material óptico transparente, bien mineral o plástico, cuyas superficies curvas le confieren cierta potencia. Para poder compensar la variación de la potencia del ojo con respecto a la longitud de onda, es necesario, como mínimo acoplarle otra lente. Para poder mantener la simplicidad del sistema se le acopla una lente difractiva cuyo comportamiento en cuanto a la variación de la potencia con respecto a la longitud de onda, la hacen idónea para el objetivo final de la invención. Para ello, se talla sobre una de las superficies de la lente inicial una lente difractiva que modula la fase del frente de onda que sale del sistema y que es capaz proporcionar, en conjunto, la variación de la potencia con la longitud de onda que compensa a la que posee el ojo humano, minimizando las aberraciones oculares residuales.The invention it consists of a system formed by a simple lens of a material transparent optic, either mineral or plastic, whose surfaces curves give it some power. In order to compensate for variation of the power of the eye with respect to the length of wave, it is necessary, at least to attach another lens. To maintain the simplicity of the system a lens is attached diffractive whose behavior regarding the variation of the power with respect to wavelength, make it ideal for The ultimate goal of the invention. To do this, it is carved on one of the initial lens surfaces a diffractive lens that modulates the phase of the wavefront that leaves the system and that is capable provide, together, the variation of the power with the wavelength that compensates for the human eye, minimizing residual eye aberrations.
El doblete está formado por una lente de vidrio o de plástico con un cierto grosor. Una de sus superficies es plana, mientras que la otra es cóncava (fig. 1). Sobre la superficie plana se encuentra la lente difractiva. Dicha lente difractiva es una lente kinoform que produce una variación en la fase del frente de onda, según un polinomio de cuarto orden a lo largo del radio del diámetro de la lente.The doublet is formed by a glass lens or plastic with a certain thickness. One of its surfaces is flat, while the other is concave (fig. 1). On flat surface is the diffractive lens. That lens diffractive is a kinoform lens that produces a variation in the wavefront phase, according to a fourth order polynomial at length of the radius of the lens diameter.
El sistema diseñado ha sido comparado con las prestaciones que ofrecen los sistemas ópticos convencionales ya existentes. Posee un comportamiento asimétrico en la MTF con respecto al plano sagital y el tangencial, siendo el del plano sagital superior al que tienen los sistemas previos. Además, el sistema diseñado tiene un mayor margen en la tolerancia a la inclinación de su eje óptico con respecto al del ojo en su acoplamiento, siendo similar la correspondiente al descentramiento.The designed system has been compared to features that conventional optical systems already offer existing. It has an asymmetric behavior in MTF with regarding the sagittal and tangential plane, being that of the plane Sagittal superior to the previous systems. In addition, the designed system has a greater margin in tolerance to inclination of its optical axis with respect to that of the eye in its coupling, similar to that corresponding to runout
Primeramente se talla la lente de vidrio, o de plástico, de diámetro adecuado, de tal manera que una de sus superficies sea plana, mientras que la otra posea un forma cóncava, y con un grosor no excesivo, tal y como se ve en la figura 1. Una vez fabricada dicha lente, se talla, sobre la superficie plana, la lente kinoform consistente en una serie de surcos en forma de anillos, cuyo espaciado y número se derivan de la variación de la fase del frente de onda y que corresponde a un polinomio de cuarto grado con el radio del diámetro de la superficie, y que tiene la expresión:First the glass lens is carved, or plastic, of adequate diameter, such that one of its surfaces are flat, while the other has a concave shape, and with a non-excessive thickness, as seen in figure 1. A once said lens is manufactured, the carving is carved on the flat surface. Kinoform lens consisting of a series of grooves in the form of rings, whose spacing and number are derived from the variation of the phase of the wavefront and corresponding to a fourth polynomial degree with the radius of the surface diameter, and that has the expression:
\Phi (r) = 2\pi /\lambda (A_{2}r^{2} + A_{4}r^{4}).\ Phi (r) = 2 \ pi / \ lambda (A 2 r 2 + A 4 r 4).
