1. An optical lens assembly, comprising:
a diaphragm, a zoom lens group, a light deflecting assembly and a compensating lens group sequentially arranged along an optical axis and from an object side to an imaging plane;
wherein the optical axis comprises a first optical axis segment between the diaphragm and the light deflecting assembly, and a second optical axis segment between the light deflecting assembly and the compensating lens group; the zoom lens group is located on the first optical axis segment, and the first optical axis segment is different from the second optical axis segment;
wherein the compensating lens group comprises a first compensating lens, a second compensating lens and a third compensating lens; a light incident surface and a light emitting surface of the first compensating lens are both convex; a light incident surface of the second compensating lens is convex, and a light emitting surface of the second compensating lens is concave; and a light incident surface and a light emitting surface of the third compensating lens are both concave, and
wherein the second compensating lens is located between the first compensating lens and the third compensating lens, and the first compensating lens, the second compensating lens and the third compensating lens are arranged adjacently.
