Abstract
An optical device includes a light shielding wall including a light shielding portion that shields light from a light source, a first through-hole and a second through-hole that allow passage of light from the light source, the second through-hole having a smaller diameter than the first through-hole, and a cutout portion that forms the second through-hole, a microlens array configurated by a plurality of lenses that condenses light having passed through the first through-hole and the second through-hole, and an image sensor that reads the light condensed by the microlens array.

An optical device comprising:
- a light shielding wall including a light shielding portion that shields light from a light source, a first through-hole and a second through-hole that allow passage of light from the light source, the second through-hole having a smaller diameter than the first through-hole, and a cutout portion that forms the second through-hole;
- a microlens array configurated by a plurality of lenses that condenses light having passed through the first through-hole and the second through-hole;
- and
- an image sensor that reads the light condensed by the microlens array.
An optical device comprising:
- a light shielding wall including a light shielding portion that shields light from a light source, a first through-hole and a second through-hole that allow passage of light from the light source, and a cutout portion that forms the second through-hole;
- a microlens array configurated by a plurality of lenses that condenses light having passed through the first through-hole and the second through-hole;
- and
- an image sensor that reads the light condensed by the microlens array, wherein
- among the adjacent light shielding walls, a part of an end portion of one light shielding wall and a part of an end portion of the other light shielding wall overlap with each other in a longitudinal direction of the second through-hole.
An optical device comprising:
- a light shielding wall including a light shielding portion that shields light from a light source, a through-hole that allows passage of light from the light source, and a cutout portion that forms the through-hole;
- a microlens array that is configurated by a plurality of lenses that condenses light having passed through the through-hole and for which a light shielding film is provided to suppress an amount of light condensed from the through-hole formed in the cutout portion;
- and
- an image sensor that reads light condensed by the microlens array.
