Title: Relative position detector
Inventor: MAEDA HIDEO
IPC: G01B11/00
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an improved relative position detector without being affected by the movement of a scale in a direction that is vertical to the traveling direction. SOLUTION: Light from a light source 20 is projected to a scale 21 with a slit pattern, and light being reflected from the scale 21 is received by photodetectors 22 and 22'. A slit pattern SP 1 appears in a light path on the front surface of the photo detector, and the slip pattern SP 1 changes corresponding to the movement of the scale, thus moving the scale, namely detecting a position, based on the output of the photodetectors 22 and 22'. A mask 24 that has a plurality of divided regions in the light path and the slit where a scale pitch is shifted one another for each region and a condensing lens are arranged, the bottom value of an output signal is eliminated, and the utilizing efficiency of light is improved. Even when permeation light is received instead of reflected light, the position can be detected by a slit pattern SP 1' in the same manner.

Filed: 1990-07-18
Abstract: PURPOSE:To detect a small change in a synthesized output level without increasing the cost by selecting any of plural kinds of gains set by a gain variable means and operating the controller with a selected gain. CONSTITUTION:When a change in a synthesized output level per unit angle of a phase shifter 15 is smaller than a prescribed quantity set around a minimum resolution of an A/D converter 21, that is, around an optimum point, the gain of a variable attenuator 30 is decreased and an input level to the A/D converter 21 is doubled. Thus, a change in the synthesized output level per unit angle of the phase shifter 15 is doubled and reaches the minimum resolution of the A/D converter 21 or over. That is, the minimum resolution of the A/D converter 21 is increased equivalently. Thus, a control section 31 detects a small change around the optimum point and phase control of the phase shifter 15 is implemented accurately even around the optimum point.
