Description

one

This invention relates to a method for enlarging images and objects using spotlights.

There is a method of enlarging images of objects using point luminaires and special optical means.

The purpose of the invention — to obtain enlarged images without specially used optical tools — is achieved by creating an image of a point source from a remote illuminator near the object and the screen or pupil of the input of the optical observation system, such as an eye, is placed in front of the object within the illumination beam.

Under observation In transmitted light (a transparent object) a light source with a sufficiently small luminescence area, an image receiver, for example, an eye, and an object of observation are mounted on one straight line and the entrance pupil of the image receiver is approached to the object to the limit due to the geometric shapes of the object and reference point

the images, after which they observe the resulting picture.

When viewed in reflected light (an opaque object), the light source, the image receiver and the object of observation are placed on a broken line, the break point of which is on the object of observation, and the rest of the techniques are the same as above.

Subject invention

A method for enlarging images of objects using point illuminators, and so on, so that, in order to obtain enlarged images without specially used optical means, an image of a point source from a remote illuminator and a screen or pupil of the optical system are formed near the object Observations, such as eyes, are placed in front of the object "inside the illuminating beam of rays.
