Abstract
Embodiments described herein generally relate to: sensing and/or authentication using luminescence imaging; diagnostic assays, systems, and related methods; temporal thermal sensing and related methods; and/or to emissive species, such as those excitable by white light, and related systems and methods.
Claims20
A system, comprising:
- a radiation source configured to generate electromagnetic radiation for exciting an emissive species such that the emissive species produces a detectable non-steady-state emission during an emission time period of the emissive species, the emission time period being at least 10 nanoseconds;
- a sensor configured to:
- detect, during a first portion of the emission time period, a first emission from the emissive species, and
- detect, during a second portion of the emission time period, a second emission from the emissive species;
- and
- processing circuitry configured to identify a characteristic of the emissive species based on a difference between a property of the first emission detected during the first portion of the emission time period and a property of the second emission detected during the second portion of the emission time period.

A system comprising:
- a radiation source configured to generate electromagnetic radiation for exciting an emissive species such that the emissive species produces a detectable non-steady-state emission during an emission time period of the emissive species;
- an electromagnetic radiation sensor configured to sense during a single exposure:
- first emission from the emissive species during a first portion of the emission time period, and
- second emission from the emissive species during a second portion of the emission time period;
- and
- processing circuitry configured to identify a characteristic of the emissive species based on a difference between a property of the first emissions detected during the first portion of the emission time period and a property of the second emissions detected during the second portion of the emission time period.

A method for identifying a characteristic of an emissive species, comprising:
- generating electromagnetic radiation;
- exciting, using the electromagnetic radiation, an emissive species such that the emissive species produces a detectable non-steady-state emission during an emission time period of the emissive species;
- detecting, during a first portion of the emission time period, a first emission from the emissive species, and
- detecting, during a second portion of the emission time period, a second emission from the emissive species;
- and
- identifying, using processing circuitry, the characteristic of the emissive species based on a difference between a property of the first emission detected during the first portion of the emission time period and a property of the second emission detected during the second portion of the emission time period.
