{"title":"The optical quality of the monochromatic retinal image as a function of focus.","authors":"W N Charman,&nbsp;J A Jennings","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Changes in retinal image quality with focus for an aberration-free eye with a 5-mm pupil are discussed in terms of both geometrical and physical optics. Further modulation transfer function curves illustrate the effect of spherical aberration. These theoretical results are compared with analogous experimental data obtained at different wavelengths with quasi-monochromatic illumination, using a double-pass photo-electric, scanning instrument. The comparison shows that the approximations of geometrical optics predict ocular performance quite well, provided that the errors of focus are reasonably large (greater than or equal to 0.5 DS for a 5-mm entrance pupil). Possible sources of error in the experimental measurements are indicated.</p>","PeriodicalId":76613,"journal":{"name":"The British journal of physiological optics","volume":"31 3","pages":"119-34"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12232617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent developments in automatic refraction. 自动折射的最新进展。

{"title":"Recent developments in automatic refraction.","authors":"H A Knoll","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A detailed description of the Ophthalmetron is given. This is an automatic refractometer using the principle of infra-red retinoscopy and having a sensitivity range from -18.00 D to +17.00 D with a resolution of 0.25 D. By means of a rapid light scan across the patient's pupil the instrument determines the direction of motion of the retinal reflex in all meridians and a movement null-point is determined electronically. Results are then plotted automatically on a chart drum. Some early validation studies have shown the Ophthalmetron to provide a refraction end-point in good agreement with conventional retinoscopic findings. The paper concludes with an appendix in which the features of three commercially available automatic refractometers are compared.</p>","PeriodicalId":76613,"journal":{"name":"The British journal of physiological optics","volume":"31 4","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"1976-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12233666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
