Title: Infrared ray image pick-up device
Inventor: KIYOTA TAIJIRO
IPC: G01J5/48
Filed: 1992-05-12
Abstract: PURPOSE:To obtain an infrared ray image pick-up device with a stable output signal by eliminating influence of atmosphere which differs depending on each wavelength. CONSTITUTION:Unit picture elements of a detector 4' are constituted by detection elements and wavelength band limitation materials with different wavelength band limitations are added to the detection elements within the unit picture elements. Then, a compensation coefficient where a compensation coefficient storage system 8 eliminates the influence of thermal radiation of atmosphere is calculated according to the output of the detection elements when a shutter 20 in front of an optical system 2 is opened for collimating atmosphere and that of the detection elements when the shutter 20 is closed for collimating a reference black body and then is stored. When a target 1 whose image should be picked up is collimated, an operator 11 adds the compensation coefficient to the output of the detection elements and then obtains a signal where the influence of thermal radiation of atmosphere is eliminated.

At this time, the light outputs 5, 6 are outputted as the same polarized wave as the polarized wave of the incident light regardless of the cross or bar state.  The bar state is attained in the case where the polarized wave is not rotated by the polarization plane rotating element 1 and the cross state is attained in the case where the polarization plane 15 rotated 90 deg. by the polarization plane rotating element 1 when the light inputs 3, 4 to the switch are polarized to the S polarized waves.

A phosphorus compd. in the incinerated ash is reduced to form elemental phosphorus, and the elemental phosphorus is volatilized as a phosphorus vapor by this heating. Then, the incinerated ash from which the phosphorus is removed is discharged from the heating furnace. The treated ash is decreased remarkably in phosphorus content and modified so that it can be used as a cement source.  On the other hand, the volatilized vapor or the elemental phosphorus is incorporated in the waste gas and discharged from the heating furnace and sent to a waste gas treating stage removing the phosphorus.
