Abstract

The invention relates to a mirror for focusing electromagnetic radiation. The essence of the invention is that a reflective mirror surface 6 is established on a supporting structure, created by the rotation of elliptical arcs, where the first foci C1 of all elliptical arcs lie on one line and the second foci C2 of all elliptical arcs lie at one fixed point. Each elliptical arc is a part of an ellipse described in a Cartesian coordinate system (x, y, z) by the following equation: y 2 = b 2 1 − x 2 b 2 + c z 2 <img class="EMIRef" id="551f11c0-42a8-4fb8-a557-b760fcecee0a-ia01" /> where z is independent of x and y, c(z) is the focal distance of the rotated elliptical arcs dependent on z, b is the minor axis of the ellipse, and each ellipse has the same position of the second focus at the point (x = -c, y = 0, z = 0). Each ellipse is rotated around the rotational line 4 (x = -c, y, z = 0), where c is the focal distance corresponding to the distance from the focus to the center of the ellipse placed in the plane {x, y, 0}. Each point in the series C1(z) of the first foci of the rotated elliptical arcs is positioned on the focal line. The invention also relates to a method for focusing electromagnetic radiation and converting it into an electrical signal. The essence of the method is that the above-defined reflective mirror surface focuses radiation from a line source placed parallel to the series of first foci of the rotated elliptical arcs to at least one point on a line parallel to the second focal line. The intensity of the electromagnetic radiation is detected at this point and converted into an electrical signal by changing the electrical characteristic of a photosensitive element in the detector, from which the course of the electromagnetic radiation in time and space is determined. The invention further relates to a device for focusing electromagnetic radiation and converting it into an electrical signal. The essence of the device is that the mirror body 7, on its supporting structure, has the above-defined reflective mirror surface 6. At least one detector 13 of electromagnetic radiation is associated with this mirror body, placed on a line parallel to the second focal line, and connected to a recording device 20.
