Title: OPTICAL MODULE AND DISTANCE MEASUREMENT DEVICE
Abstract:
The purpose of the present invention is to provide an optical module capable of precisely acquiring information associated with the deflection angle of a mirror, and a distance measurement device equipped with the optical module. The optical module according to the present invention comprises a support (2), moving parts (3,4) supported to pivot around axial lines (X1, X2) in the support (2), a mirror (7) provided on the moving parts (3, 4), driving coils (11, 12) provided on the moving parts (3, 4), a temperature monitoring element (14) provided on the support (2), and a magnet (30) for generating a magnetic field acting on the driving coils (11, 12). The support (2) is thermally connected to the magnet (30).
