Title:
POLARIZATION BEARING DETECTION TYPE TWO-DIMENSIONAL LIGHT RECEPTION TIMING DETECTING DEVICE AND SURFACE SHAPE MEASURING DEVICE USING IT
Document Type and Number:
WIPO Patent Application WO/2003/074967
Kind Code:
A1
Abstract:
A polarization bearing detection type two-dimensional light reception timing detecting device for implementing a fast surface shape measurement that can accommodate an animal body measurement, and a surface shape measuring device using it. In Fig. 8, the polarization bearing of a detection light is turned in synchronization with slit light scanning, and the polarization bearing is two-dimensionally recorded by two sets of analyzers (5, 6) and storage type image detectors (7, 8) in a crossed Nicols arrangement, thereby it is possible to determine, with only one-time imaging, timing at which a slit light is beamed into respective pixels in the storage type image detectors (7, 8).
