Abstract
A system is presented in accordance with aspects of the present disclosure. In various embodiments, the system includes a light source configured to emit light, an emitting lens positioned to obtain the emitted light and configured to produce a shaped beam, an optical element positioned to obtain the shaped beam and redirect the shaped beam toward a near field object to produce scattered light from the near field object, and to obtain and redirect at least a portion of the scattered light, and a collection lens configured to focus the at least the portion of the scattered light on a light detector.
Claims20
A system comprising:
- a light source configured to emit light;
- an emitting lens positioned to obtain the emitted light and configured to produce a shaped beam;
- an optical element including a mirror having a rotational axis, the optical element positioned to:
- redirect the shaped beam toward a near field object to produce scattered light from the near field object, and
- redirect at least a portion of the scattered light;
- and
- a collection lens configured to focus the at least the portion of the scattered light that is reflected from the rotational axis of the optical element on a light detector, the collection lens including a tangential plane,
- wherein the emitting lens includes a tangential plane coincident with the rotational axis of the optical element and coincident with the tangential plane of the collection lens.
A method comprising:
- emitting light from a light source;
- producing a shaped beam by an emitting lens positioned to obtain the emitted light;
- redirecting, by an optical element, the shaped beam toward a near field object to produce scattered light from the near field object;
- redirecting, by the optical element, at least a portion of the scattered light;
- and
- focusing, by a collection lens, the at least the portion of the scattered light that is reflected from a rotational axis of the optical element or the at least the portion of the scattered light that is at an intersection of the optical element and a tangential plane of the collection lens on a light detector.
A system comprising:
- a light source configured to emit light;
- an emitting lens positioned to obtain the emitted light and configured to produce a shaped beam;
- an optical element including a mirror having a rotational axis, the optical element positioned to:
- obtain the shaped beam and redirect the shaped beam toward a near field object to produce scattered light from the near field object, and
- obtain and redirect at least a portion of the scattered light;
- and
- a collection lens configured to focus the at least the portion of the scattered light that is at an intersection of the optical element and a tangential plane of the collection lens on a light detector,
- wherein a sagittal plane of the collection lens and a sagittal plane of the emitting lens are coincident, and
- wherein the collection lens and the emitting lens are distributed on a left side and a right side, respectively, of the rotational axis of the mirror.
