1. A system, comprising:
a light source configured to emit infrared light at a wavelength of about 905 nm or about 1550 nm, wherein the light source comprises a floodlight configured to illuminate a scene;
an image sensor configured to generate image data based on the infrared light received at the image sensor;
a primary lens positioned to direct the infrared light from the scene onto the image sensor; and
an array of microlenses positioned between the image sensor and the primary lens, each microlens configured to focus the infrared light from the scene onto a corresponding portion of the image sensor,
wherein the system is incorporated into a sensor positioned on an autonomous vehicle.
