2-d straight-scan on imaging surface with a raster polygon
A 2-D scanning system uses a fast-rotating raster-polygon as a single scanning component to produce straight scan lines over a 2-D image surface. An approach angle of incident light beams to the raster-polygon is selected to minimize pin-cushion distortion of scan lines introduced by polygon scanning on the image surface, and a tilt angle of the rotational axis of the raster-polygon is selected to position said polygon-scanning distortion symmetrically on the image surface. In addition, scan optics are configured to generate a predetermined amount of barrel distortion of scan lines on the image surface to compensate for pin-cushion distortion introduced by polygon scanning.

The implementation cost of a line scanning optical coherence tomography (OCT) device is reduced by minimizing the size of the scanning mirror and using a light source with lower intensity uniformity requirements. And the scanning mirror reflects the detection light beam to different parts of the sample so as to carry out line scanning on the sample. Before the light beam reaches the reflector, the linear compression lens compresses the section length of the detection light beam, so that the reflector is miniaturized, and only the compressed light beam is reflected. When a linear beam of the probe beam is generated, a cascade of the collimating lens, the Powell lens, and the focusing lens generates a linear beam from an original beam of the point light source. The slit further filters the linear beam to remove its peripheral portion such that the intensity of the linear beam is substantially uniform even if an asymmetric divergent light source is used.
