ABSTRACT OF THE DISCLOSURE The photoelectric detector contains a photosensor or light-sensing element of a pyroelectric polymer film inter- posed by two disurbance-preventive chambers such that the two disturbance-preventive chambers are designed so as to equalize the pressures therein to ambient pressure. The photoelectric detector undergoes no or little disturbance from the ambient atmosphere, thereby permitting an accurate detection or measurement of light or beams detected by the photosensor or light-sensing element mounted in the detector.
