Abstract
An optical projection system capable of detecting projection image deformation is provided. The optical projection system includes a laser source system, a scan unit, a detection unit and a signal control processing unit. The laser source system generates a visible laser having a visible wavelength and a detection laser. The scan unit projects the visible laser and the detection laser onto a projection plane, and drives the visible laser and the detection laser to scan along multiple scan lines to form a projection image. The detection unit detects the detection laser reflected by the projection plane, and outputs a voltage signal. The signal control processing unit determines whether the projection image is deformed according to the voltage signal, and accordingly determines whether to perform a correction operation.
