NEW COLOR TV CAMERAS FOR ULTRAVIOLET, NEAR-INFRARED AND VISIBLE-LIGHT

Two kinds of TV cameras have been developed that are capable of showin g the wavelengths of ultraviolet, infrared, and visible light by means of a false color method. One is sensitive to wavelengths from 250 to 650 nm (ultraviolet to yellow), It can simulate the color vision of th e honey bee and other insects, reproducing the nectar guide of a flowe r or displaying the sex of a cabbage white moth, which is indistinguis hable to the naked eye. The other is sensitive to a wider wavelength o f 250 to 1,050 nm (ultraviolet to near infrared). According to the fil ter selected, it obtains not only visual images of invisible light inf ormation but also pictures same as those from an ordinary color camera . These TV cameras can be applied in many fields, including science, a rt, medicine, and industry.
