Abstract: An imaging apparatus includes a light source that emits pulsed light, a reflective encoding device, and an image sensor. The reflective encoding device includes first and second films each having light-transmitting property and light-reflecting property and a modulator disposed between the first and second films. The modulator includes modulation regions arrayed in one plane intersecting an optical path of the pulsed light and each modulating at least one of a degree of polarization, a phase, and an intensity of incident light. The image sensor receives light from a target and outputs one or more electric signals representing an image of the target on the basis of the light from the target. The reflective encoding device allows the pulsed light to undergo multiple reflection between the first and second films and allows a portion of the pulsed light to be emitted through the second film in multiple instances.

Abstract: An imaging apparatus includes a light source that includes a diffusion plate and, in operation, emits, toward a subject, pulsed light that diverges; a photodetector that includes a photoelectric converter that, in operation, receives light from the subject and converts the light to an electric charge and an electric charge accumulator that, in operation, accumulates the electric charge, and, in operation, generates an electric signal based on the accumulated electric charge; and a control circuit that, in operation, controls the light source and the photodetector. The control circuit, in operation, causes the electric charge accumulator to start accumulating the electric charge when a period of time has passed after the control circuit has caused the light source to start emitting the pulsed light, and causes the electric charge accumulator to accumulate the electric charge corresponding to a component, among the light from the subject, that is scattered inside the subject.
