Abstract
The invention relates to a lensless imaging device, comprising an emitting part comprising a light source (1) configured to emit a light beam in a direction of emission and intended to follow an optical path, a receiving part incorporating an electronic circuit board (3) bearing a sensor (2) having a planar capture surface (20) intended to receive said light beam in a direction normal to said capture surface, said optical path being subdivided into several successive optical sections, each optical section corresponding to a distinct direction of propagation of the light beam.
Claims9
A lensless imaging device, comprising:
- an emitting part comprising a light source configured to emit a light beam in a direction of emission and configured to follow an optical path,
- a receiving part incorporating an electronic circuit board bearing a sensor having a planar capture surface configured to receive that said light beam in a direction normal to said capture surface,
- said optical path being subdivided into several successive optical sections, each optical section corresponding to a distinct axis of propagation of the light beam,
- wherein:
- the first optical section (T_1) of the optical path starts from the light source to a first optical element,
- the last optical section (T_N) of the optical path starts from a last optical element and is oriented in a direction normal to the capture surface of the sensor,
- the optical path comprises, among the several successive optical sections, at least two successive optical sections which are of distinct axis and which are situated in a plane parallel to the capture surface of the sensor.
