Abstract :
Two kinds of TV cameras have been developed that are capable of showing 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 the honey bee and other insects, reproducing the nectar guide of a flower or displaying the sex of a cabbage white moth, which is indistinguishable to the naked eye. The other is sensitive to a wider wavelength of 250 to 1,050 nm (ultraviolet to near infrared). According to the filter selected, it obtains not only visual images of invisible light information but also pictures same as those from an ordinary color camera. These TV cameras can be applied in many fields, including science, art, medicine, and industry
