Abstract

OCT sensors traditionally use scanning optical delay lines with moving parts and a single detector. Compared to this OCT systems with a linear detector array (linear OCT or LOCT) are very simple and robust, but a detector with approximately 10 ⁴ pixel is needed for a imaging depth of 2 millimeter. We present a new system for LOCT which extends the measurement range of LOCT systems by attaching a mask on the image sensor. The mask essentially performs a down conversion of the spatial frequencies by multiplication with a second spatial frequency. We use this effect to reduce the fringe frequency of the OCT signal so that sampling and calculating the modulation of the signal can be done with relatively few pixels. The theory for this approach is addressed and first measurements are presented.
