Abstract

The invention relates to movable light target angular measure probe. Its technology scheme is as follows: it includes photic slit, lens hood, linear CCD, slit projecting light; the lens hood is closed hollow hexahedron on which rectangular coordinate system is set; one side wall center is coordinate origin 'O'; upright center line is OY axes; level center line is OX axes; the connecting line between the 'O' point and the corresponding side wall center is OZ axes; linear CCD is set at the side wall level center line; and its midpoint is coincided with the coordinate origin 'O'; another side wall upright center line is set photic slit of which center the OZ axes is passed through. The slit projecting light is fallen on the side wall inner and normal to the linear CCD. The photic slit faces to movable light target while using.

Description

1. Technical field [0001] The invention belongs to an angle measuring probe related to the technical field of photoelectric measurement. 2. Technical background [0002] The so-called moving light target means that the position of the light target in space will change as time goes by. For observers, it is necessary to produce an angle change with the observation position, such as the sun, which is a huge moving light source, with sunrise in the east and sunset in the west every day. For observers, the space azimuth and elevation angle of the sun are changing at any time. Measuring the instantaneous angle change with the sun is very meaningful for industrial and agricultural production, scientific research, and utilization of solar energy. For another example, jet engine flame vents and rocket engine flame vents can be regarded as moving light targets in the air, and as time goes by, they also have angle changes relative to the observer. Measuring the instantaneous angle c...
