Title:
LIGHT PROPAGATION TIME CAMERA SYSTEM HAVING SIGNAL PATH MONITORING
Document Type and Number:
WIPO Patent Application WO/2012/013760
Kind Code:
A1
Abstract:
The invention relates to a light propagation time camera system (1), comprising a photosensor (22), which has at least one receiving pixel, further comprising an illumination light source (10, 12) and a modulator (30), which supplies a modulation signal for the photosensor (22) and the illumination light source (10, 12), wherein a control sensor (150) is arranged in the region of the illumination light source (10, 12) such that the control sensor (150) can receive at least some of the radiation emitted by the illumination light source (10, 12), and the control sensor (150) provides an output signal which characterizes the temporal intensity progression of the radiation that is received, and the control sensor (150) is connected to at least one reference light source (260, 270) or an electric mixer.
