A imagem de alcance de tempo de voo (TOF) é uma tecnologia promissora para diversas aplicações, como controle sem toque, interface de realidade aumentada e automotiva. Os geradores de imagens da faixa TOF são classificados em dois métodos: TOF direto com diodos de avalanche de foto única e TOF indireto com pixels lock-in. Os geradores de imagens de alcance TOF indireto têm vantagens em termos de alta resolução espacial e alta precisão de profundidade porque seus pixels são simples e podem lidar com muitos fótons ao mesmo tempo. Este artigo revisa e discute os principais pixels lock-in relatados no passado e no presente, incluindo pixels lock-in baseados em circuitos e moduladores de carga. Além disso, também são discutidas tecnologias-chave que incluem técnicas de aumento de sensibilidade e supressão de fundo.

Abstract: Time-of-flight (TOF) range imaging is a promising technology for various applications such as touchless control, augmented reality interface, and automotive. The TOF range imagers are classified into two methods: direct TOF with single photo avalanche diodes and indirect TOF with lock-in pixels. The indirect TOF range imagers have advantages in terms of a high spatial resolution and high depth precision because their pixels are simple and can handle many photons at one time. This paper reviews and discusses principal lock-in pixels reported both in the past and present, including circuit-based and charge-modulator-based lock-in pixels. In addition, key technologies that include enhancing sensitivity and background suppression techniques are also discussed.
