The paper contains info around linearity, modulation signal, image sensor, linearity error, photodetector, optical, and measurement sensor. Lots of discussion such as modulation, signal, sensor, frequency, optical distance measurement, sensors, and deviation are presented in this paper.
Inside this paper you can read description like distance, resolution, measured linearity error, detector, measurement range, error, and measurement. The following are excerpted from this paper:
Instrumentation and Measurement Technology Conference – IMTC 2007 Warsaw, Poland, May 1-3, 2007 Monolythically Integrated Optical Distance Measurement Sensor with Double-Cathode Photodetector Klaus Oberhauser, Gerald Zach, Alexander Nemecek, Horst Zimmermann Institute of Electrical Measurements and Circuit Design, Vienna University of Technology Gusshausstr. s max = Icath1 p- ϕ vp t delay − t tof = Vmod ( t ) ⊗ Popt ( t − t tof ) = = Vanode cathode1 The distance information represented by the phase-shift between the electrical modulation signal Vmod and the received optical signal Popt can be reconstructed by measuring the cross-correlation function φvp given by eq.
Furthermore, the paper explains information things like distance measurement, standard deviation, distance measurement sensor, output, the distance measurement, and measurement characteristic.
