Investigation of optical characteristics of rigid protected and traditional elastic Fresnel microprisms using electronic method for measuring visual acuity
چکیده انگلیسی
A method for determining resolution of images through prisms using test patterns is proposed. This technique is more precise than the traditional method for measuring visual acuity, which involve ophthalmologic test charts and questioning patients. An experimental setup allowing the measurement of image resolution was developed. Comparative characteristics were obtained for “Gulden Ophthalmics“ (USA) monoprisms, for “3M™Press-On™” (USA) elastic films with microrelief and for new rigid protected Fresnel microprisms developed at the Institute for Information Recording (Ukraine). The reasons for the decrease in image resolution and visual acuity are discussed for all of the investigated ophthalmic monoprisms and microprisms.
