Title: Photoelectric axial-angle converter
Inventor: BIRU BERU
IPC: G01B11/26
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain an axial angle converter having high linear response, high S/N ratio and small dimensions at low cost by a structure wherein a larger quantity of light impinges on one photosensor and a smaller quantity of light impinges on the other photosensor as a light patch translates with a linear relationship being set between the difference in the quantity of light impinging on both sensors and the angular displacement of axis. SOLUTION: An axial angle converter 100 is coupled with a shaft 102 in order to measure the angular displacement of shaft 102 around the Z-axis 104 of rotation. An LED 106 projects a light beam 108 along the X-axis 110 on photosensors 114, 116 through an optical assembly 312. The X-axis 110 is perpendicular to the Z-axis 104 and passes between the sensors 114, 116. Subsequently, the beam 108 passes through a prism 120 and an aperture 124 before impinging on the sensors 114, 116. Photosensitivity of the photosensor varies with temperature but the temperature difference is minimized between both sensors. The electric circuit generates a raw force signal from the difference of signals produced from the sensors 114, 116.
