Optical system for light detection and ranging

An optical transmitter, comprising:

• an emitter array comprising a plurality of optical emitters,
• wherein the emitter array is configured for solid-state line scanning;
• and
• wherein the emitter array has a first aspect ratio;
• and
• a set of transmission optics configured to receive light from the emitter array and to illuminate a field of view having a second aspect ratio that is greater than the first aspect ratio,
• wherein a horizontal dimension of the field of view is at least two times greater than a vertical dimension of the field of view.

An optical receiver, comprising:

• an image sensor array configured for line readout,
• wherein the image sensor array is to receive light, from an emitter array having a first aspect ratio, that is reflected from objects in a field of view having a second aspect ratio that is greater than the first aspect ratio, and
• wherein the image sensor array has a third aspect ratio that is different from the first aspect ratio and the second aspect ratio;
• and
• a set of reception optics configured to image light reflected from the objects in the field of view, having the second aspect ratio, onto the image sensor array having the third aspect ratio.
