Abstract:
The disclosure provides a focusing method of optical machine of projector, a focusing device and an optical machine. The focusing method comprises steps of: detecting deformation amount of lens of an optical machine; and controlling and adjusting a focal length of the lens of the optical machine according to the deformation amount of the lens of the optical machine. In the he focusing method, by detecting the deformation amount of the lens of the optical machine in real time and controlling to adjust the focal length of the lens of the optical machine in real time according to the deformation amount of the lens of the optical machine, the adjustment precision of the focal length of the lens of the optical machine can be greatly improved.

Claim (Index 7):
The focusing device according to  claim 6 , wherein the detection circuit comprises a deformation sensor disposed on the lens of the optical machine, a first detection sub-circuit disposed on the lens of the optical machine, and a calculation sub-circuit, wherein\n the deformation sensor is configured to detect a first deformation amount of the lens of optical machine as a function of temperature; the first detection sub-circuit is configured to detect a second deformation amount of the deformation sensor as a function of temperature; and the calculation sub-circuit is configured to calculate the deformation amount of the lens of optical machine according to the first deformation amount and the second deformation amount, wherein the deformation amount of the lens of optical machine is equal to the first deformation amount minus the second deformation amount.
