Abstract

PURPOSE:To output the number of pulses according to ultraviolet rays dose by converting the input of light into an electrical change with irradiation of relatively short wave length light to a gate of an MOS transistor composing a light sensor. CONSTITUTION:While a voltage of a power source E is applied between a drain 2 and source 3 of an MOS transistor, a certain voltage ER generates an negative charge on a gate 5 covered with an insulation film 4 when applied on the gate 5 from an electronic switch S. Then, when the electronic switch S is opened, the charge is left on the gate 5 while the gate 5 retains the initial voltage ER. Under such a condition, when a light with a short wave length of about less than 4,000Angstrom enters, the working point of the transistor moves. Thus, electric changes can be obtained according to the entry of the light of such a short wave length. The transistor provides an ideal ultraviolet rays sensor because of virtual insensitivity to light of a long wave length.
