Abstract

PURPOSE:To obtain a highly sensible optical detector not lowering a pyroelectric property secularly, by extending a high molecular film having the pyroelectric property in order that the quantity of strain in a direction in which an expansion and contraction piezo-electric property becomes maximum is in a specific range and holding said film on a frame body. CONSTITUTION:Electrodes are formed on both sides of a piezo-electric high molecular film such as polyvinylidene fluoride etc. whcih is carried out one axis drawing and a pyroelectric high molecular film 1 having 50mu-1,000mu thickness and carried out polarization treatment by applying direct current voltage between said electrodes, is made. The film 1 is held on a frame body 2 and is held expanding in order that the quantity of strain (the quantity of strain epsilon=DELTAl/l at the time of expanding DELTAl by extension for a length l not giving tension) in a drawing direction (shown by an arrow mark 3), is in the range of 5X10<-4>-3X10<-2>. Next, a ring-shaped frame body 4 having about 100mm. diameter to which a bonding agent 5 is applied on the back, is placed on the film 1 and is fixed. Hereafter, the body 4 to which the film 1 is attached is cut off and a film having a good light absorbing property such as carbon black or gold black is formed on the surface of a light incidence side electrode and then, an optical detection apparatus is obtained.
