Abstract
A light detection system is provided for association with a light source. The light detection system includes a light detector and circuitry. The light detector includes semiconductor film and phototube devices and is disposed with at least one line-of-sight (LOS) to the light source. The circuitry is coupled to the light detector and the light detector and the circuitry are configured to cooperatively identify a presence and a characteristic of a light emission event at the light source.

A light detection system for association with a light source, the light detection system comprising:
- a light detector comprising semiconductor film and phototube devices,
- the light detector being disposed with at least one line-of-sight (LOS) to the light source;
- and
- circuitry coupled to the light detector, the light detector and the circuitry being configured to cooperatively identify a presence and a characteristic of a light emission event at the light source.
A light detector, comprising:
- a first wafer having opposed first and second major surfaces;
- a photosensitive semiconductor film disposed on the second major surface of the first wafer;
- interdigital electrodes (IDEs) partially formed on the photosensitive semiconductor film;
- a second wafer having opposed first and second major surfaces;
- and
- a top electrode disposed on the first major surface of the second wafer,
- the first and second wafers being bonded such that the respective second and first major surfaces of the first and second wafers face each other with a cavity defined between the respective second and first major surfaces of the first and second wafers, and
- the cavity being chargeable with gas supportive of photoelectric phenomena between the IDEs and the top electrode.
A method of assembling a light detector, comprising:
- disposing a photosensitive semiconductor film on a major surface of a first wafer;
- partially forming interdigital electrodes (IDEs) on the photosensitive semiconductor film;
- disposing a top electrode on a major surface of a second wafer;
- bonding the first and second wafers such that the respective major surfaces face each other with a cavity defined therebetween;
- and
- charging the cavity with gas supportive of photoelectric phenomena between the IDEs and the top electrode.
