Embodiment Construction
[0032] The following embodiments will further describe the present invention in conjunction with the accompanying drawings.
[0033] like figure 1 As shown, a space-borne high-angle resolution laser warning detection device is mainly divided into two parts: the first part is composed of a blazed grating 1, a short-focus lens 2 and a focal plane detector 3 to roughly measure the laser wavelength and angle module; the second part is a high-precision angle positioning measurement module composed of a lens array 4 , a mirror 5 , a half mirror 6 and a focal plane detector 3 . The first part provides preliminary laser angle information, and provides corresponding parameters for the second part to select a specific lens. like figure 1 As shown, the focal point of each lens is located at the center of the focal plane detector 3 . Each lens detects a different position, but all the lenses share one detector, which not only improves the angle positioning accuracy, but also reduces th...
