Array structure of photosensitive device and photoelectric encoder

Abstract

The invention relates to an array structure of a photosensitive device and a photoelectric encoder. The array structure of the photosensitive device comprises a photosensitive device array and a housing. Two coding window units in opposite to the photosensitive device array and a signal window unit arranged between the two coding window units are arranged at the housing. Each coding window unit includes at least two columns of coding windows, wherein the two adjacent columns of coding windows are intersected. Therefore, the array structure dimension of the photosensitive device is reduced under the condition of having the same number of coding windows and thus the size of the photoelectric encoder is reduced; and the photoelectric encoder can reach the resolution in a linear arrangement manner.

Description

technical field [0001] The invention relates to the technical field of photoelectric encoders, in particular to an array structure of photosensitive devices and a photoelectric encoder. Background technique [0002] The photoelectric encoder is a kind of angle measuring equipment integrating optics, mechanics and electricity. It converts the optical signal into an electrical signal through the mechanical structure and signal processing circuit, so as to realize the direct or direct measurement of various physical quantities such as angular displacement, speed and position. indirect measurement. [0003] At present, in order to improve the resolution of the photoelectric encoder, the number of photosensitive devices in the array structure of the photosensitive device is often increased, which will result in a larger size of the array structure of the photosensitive device, thereby resulting in a larger size of the photoelectric encoder. [0004] Therefore, how to simultaneou...

Problems solved by technology

[0003] At present, in order to improve the resolution of photoelectric encoders, the number of photosensitive devices in the array structure of photosensitive devices is often increased, which will cause the size of the array structure of photosensitive devices to be larger, which in turn will cause the size of the photoelectric encoder to be larger.
