摘要： A driving device including a light emitter, a biasing circuit, a light receiver, an automatic control system, and an alternating current (AC) path is disclosed. The light emitter generates an optical signal. The biasing circuit generates a driving signal to activate the light emitter such that the light emitter operates in a working range. The light receiver detects the output power of the optical signal for generating a corresponding electrical signal. The automatic control system adjusts the driving signal according to the corresponding electrical signal such that the output power of the optical signal approaches a preset value. The AC path is coupled between the light emitter and an external signal source for receiving at least one AC modulated signal such that the light emitter generates at least one modulated optical signal.

摘要： A distance measurement apparatus includes a first and a second optical signal producing units, an optical mixing unit, an electric mixing unit and a processing unit. The first optical signal producing unit includes a first emitting unit to emit a first beam based on a first modulated signal to a target. The second optical signal producing unit includes a second emitting unit to emit a second beam based on a second modulated signal. The optical mixing unit produces an optical mixing signal based on the second beam and a reflected beam of the first beam reflected by the target. The electric mixing unit produces an electric mixing signal based on the first and the second modulated signals. The processing unit calculates a phase difference based on the optical mixing signal and the electric mixing signal to determine a distance between the target and the laser ranging apparatus.
