Abstract

PURPOSE:To make an infrared image coincide with a visible image by separating light from an object into infrared rays and visible rays and guiding the visible rays to a visible rays television camera. CONSTITUTION:Light from the object 1 are separated into infrared rays 10 and visible rays 11 by a filter 9 reflecting the visible rays and passing the infrared rays. The infrared rays 10 are inputted to an infrared ray television camera body 2 as they are and the visible rays 11 reflected by the filter 9 are guided to the vidual light television camera 3 arranged on the same case 4 by a reflector 12 or the like. Since the infrared rays and the visible rays are reached to the infrared ray television camera having said constitution through the same optical path, the infrared image can be made to coincide with the visible image precisely even if a distance up to the object is near.

As a method of measuring the temperature distribution of an object without touching the object, an infrared sensor is used to measure the amount of infrared rays emitted by the object depending on its own temperature, and the temperature distribution is measured on a monitor TV. A device called an infrared television camera that displays images on a screen is widely used in industrial and medical fields, as well as in physical and chemical research.

In these cases, the temperature distribution image obtained by an infrared television camera (hereinafter simply referred to as an infrared image) is generally very different from the visible light image seen by the human eye (hereinafter simply referred to as a visible image). It is often a question of which part of the actual object the infrared image corresponds to. In order to solve this problem, conventionally, as shown in FIG. 1, a visible light television camera 3 is installed on the same housing 4 in parallel with the infrared television camera body 2, and visible images obtained by the visible light television camera are installed. There was an infrared television camera that displayed a one-to-one correspondence between an infrared image and a visible image by displaying both the infrared image and the visible image on the same monitor television. However, in this conventional device, unless the distance to the object 1 is sufficiently larger than the distance between the infrared television camera body 2 and the visible light television camera 3 in FIG. Since the optical path 5 of infrared rays and the optical path 6 of visible rays are not the same and have a finite angle, it has been impossible to accurately match the infrared image and the visible image. Furthermore, when the window for measuring temperature distribution is very small, such as when the object is in a vacuum container, in the conventional device, the light beam incidence ri 7 in FIG.

In some cases, it could not be applied because the width was greater than the interval between the two.

In an infrared television camera with such a structure, the red light and visible light from the object reach the infrared television camera through the same optical path, so even if the distance to the object is close, the infrared image and It is possible to accurately match the visible image. Furthermore, since the light beam entrance lower can be made smaller than the above-mentioned conventional device, it can be applied even when the window for measurement is small.゛In addition, in Fig. 2, instead of the filter 9 that reflects visible rays and passes infrared rays, a filter that reflects infrared rays and passes visible rays is used to construct the infrared television camera body 2.
The same effect can be obtained even if the position of the visible light television camera 3 is reversed.
