Title: Encoder
Inventor: HAINTSU BUUKAA
IPC: G01D5/30
Filed: 1989-03-24
Abstract: PURPOSE: To obtain an inexpensive encoder by eliminating the need of any tracking servo mechanism from the encoder by forming the pits of a scale board carrying a large number of pits on its surface as scale divisions longer in the direction perpendicular to the scanning direction of a laser spot. CONSTITUTION: A scale board 4 on the surface of which a large number of pits 5 are formed as scale divisions is irradiated with a laser spot 3 and reading signals of the pits 5 corresponding to the brightness of reflected light are obtained. The pits 5 are formed longer in the direction perpendicular to the scanning direction of the laser spot 3. Therefore, even when a read head is deviated from the scale board 4 in the direction perpendicular to the moving direction of the head, the pits 5 can be read surely, because the pits 5 can be surely irradiated with the spot 3. Therefore, an inexpensive encoder can be obtained, because no tracking servo mechanism is required.

Also, an angle of an analyser 5 is set so as to become 45 degrees against the double refraction intrinsic axial direction at its emitting end generated by an electric field applied to a crystal body 4. As a result, two electrodes 11 and 12 operate on the crystal body 4 as spiral electrodes, and the crystal body 4 receives an electro-optical effect. As a result, a phase difference by double refraction is varied, and the quantity of light passing through the analyser 5 is varied.

Abstract: PURPOSE:To obviate degradation in image quality by shades of nonlinear element parts and electrodes and to less degrade in an image contrast by arranging two-dimensional phase gratings which have grating patterns in two directions intersecting with each other and having a specified grating height. CONSTITUTION:A liquid crystal cell 4 is irradiated with light of a light source 1 from its rear surface side R and the two-dimensional phase gratings 5 are arranged in the display optical path 2 of the liquid crystal cell 4. The front surface side F of the phase gratings 5 is provided with a lens group 3 and the image on the liquid crystal 4 is visually observed by a viewer 6. The phase gratings 5 have the grating patterns in the two directions (X, Y) intersecting with each other. The grating heights of the respective grating patterns are fixed exclusive of errors in production. Namely, the grating patterns exist only in the two directions intersecting with each other in the phase gratings 5 and, therefore, the intensity of the diffracted light of lower order is extremely higher than the intensity of the diffracted light of higher order. Then, the degradation of the contrast by leaking of the diffracted light of the higher order to the image region of the liquid crystal cell is lessened.
