Title: Image pickup device
Inventor: NABESHIMA TAKANARI
IPC: H04N5/225
Filed: 1994-03-11
Abstract: PURPOSE:To exactly generate the first and second images of the same information, of which positions are shifted for a fixed amount on an image pickup target, at high speed. CONSTITUTION:This device is provided with a polarizing filter 32, optical retarder means 34 and birefringence filter 36 arranged between a lens 30 and an image pickup target 38. The polarizing filter polarizes a beam passed through the lens in one direction. The optical retarder means is controlled to an OFF or ON state corresponding to a control signal, applies rotation at 90 deg. to the polarizing direction of the polarized beam in the OFF state and applies no rotation in the ON state. The birefringence filter is arranged so that its principal plane formed by its optical axis together with the polarized beam can be perpendicular or parallel to the polarizing direction of the polarized beam, and the position-shifted first and second images are formed on the image pickup target by straightly advancing or refracting the image of an object corresponding to the polarizing direction of the polarized beam.

Title: Temperature measuring apparatus for object covered with transparent thin film
IPC: G01J5/00
Filed: 1992-03-26
Abstract: PURPOSE:To measure the temperature of an object having a transparent thin film formed thereon accurately by holding an emissivity detector having first and second detectors for detecting P and S polarized radiation luminance at an angle of polarization to calculate the temperature and two polarization emissivities of the object from polarization radiation luminances from the detector. CONSTITUTION:P polarization emissivity of the surface of an object 4 to be measured is neither affected by any interfering effect due to a thin film nor absorbed in the thin film with respect to P polarized light incident at a Brewster angle thetaB of polarization. So, the emissivity is constant regardless of changes in the thickness of a transparent thin film. As a result, heat radiation of the object is divided into a P polarization component and an S polarization component at a wavelength lambda and an angle thetabeta to measure and two polarization emissivities are obtained. In other words, an emissivity detector 1 having first and second detectors for detecting the P and S polarization components is provided on a holder 2 for holding the angle of thetabeta to determine two polarization radiation luminances with the detector 1 and the temperature and the emissivity of the object 4 to be measured covered with the transparent thin film made of oxide or the like are calculated with an arithmetic device 3. This enables the measuring of the temperature of the object accurately even under condition of the emissivity changing.
