TL;DR: In this article, the tracking precision of a panoramic observation and scanning instrument of a bilateral symmetry type was detected using a U-O-type rotary table as the target movement unit.

TL;DR: In this paper, a light wave polarization state high-speed static measurement was performed using photoelectricity test, where the authors proposed a high speed static measurement of the light wave in the direction of the x-axis and the y-axis.

TL;DR: In this article, the authors proposed a detection method for the orientation tracking precision of a photoelectric tracker, which successively comprises the steps of 1, placing an infinite target generator directly in front of a to-be-detected instrument, wherein the distance between the infinite target generators and the to be-detect instrument is d; 2, rotating the target generator, where the linear movement speed v of a simulated target, the rotation time omega of the simulated target and the distance d between the revolution circle center of the projected target and its rotation circle center meet the following functional relationship

TL;DR: In this article, the authors proposed an apple quality detection device consisting of a coating plane reflector, a band-pass optical filter, an imaging lens and an image sensor sequentially arranged along the optical axis direction.
