A high-precision angle measuring device and an angle measuring instrument thereof
This application belongs to the field of measurement technology, specifically a high-precision angle measuring device. The invention proposes a high-precision angle measuring device in which light emitted from a light source 1 (white LED) is directly projected onto a fan-shaped optical code disk. The fan-shaped optical code disk uses a virtual rotating axis, and the barcode image on the fan-shaped optical code disk is directly projected onto a linear array sensor. The acquired barcode digital image is sent to a microprocessor for decoding to obtain the angle value. This device achieves a high-precision angle measurement of 0.001° while also being small in size, perfectly solving the shortcomings of existing methods and achieving high precision and low cost.
