A Fresnel lens is a type of flat lens which concentrically lines up many lenses with a triangular or other cross-sectional shape along a line. It is designed so that the light refracted by each triangle passes through the same point (focal point), and has the same function as a typical lens. In a typical lens, the thickness of the material increases as you go from the periphery to the center. However, a Fresnel lens is unique in that because there is no change in thickness between the periphery and the center, it is thinner than a typical lens. Moreover, multiple lenses can be formed on one curved surface through resin formation.

Aberration meaning

3 A defect of the crystalline lens of the eye, or of any other lens or mirror, also called astigmatism or dioptric aberration, in which rays of light do not all converge on to a single focal point. In chromatic aberration, different wavelengths of light are refracted through different angles and focused at different distances, leading to blurred images with coloured fringes—see also achromatic (2), refraction. In spherical aberration light passing through the lens near its edge is focused at a different point from light passing near the lens's centre, resulting in a distorted visual image, the defect arising from the surface of the lens being spherical. [From Latin aberrare to wander away, from ab away  +  errare to wander  +  -ation indicating a process or condition]

Therefore, a lens must be used to focus the infrared rays on the element and increase the incident energy to the sensor. In addition, the detection area can be formed by determining the angle at which the lens focuses the light. That detection area is determined according to the combination of the sensor electrodes and the number of Fresnel lens segments.

Because the total energy of the infrared rays emitted from a human body is extremely low and the energy density decreases in inverse proportion to the square of the distance, the energy which enters the sensor is exceptionally small. Accordingly, optical amplification in the form of a Fresnel lens is required for reliable sensor operation in each set. When an optical system is not used in front of the sensor, the image of the sensor's directivity becomes an obscure blur of the nearby location, as shown in the figure below, and the detection area is not formed.
