1. A screening system, comprising:
a controller;
a housing;
a first temperature sensor operably connected to the controller and physically connected to the housing, the first temperature sensor having a first field of view and a first accuracy within a temperature range;
a second temperature sensor separate from the first temperature sensor, physically connected to the housing, and operably connected to the controller, the second temperature sensor having a second field of view, and having a second accuracy within the temperature range greater than the first accuracy; and
a heat source, physically connected to the housing, controllable by the controller to achieve a reference temperature within the temperature range, and disposed at least partly within the first field of view of the first temperature sensor and at least partly within the second field of view of the second temperature sensor,
the first temperature sensor being configured to simultaneously determine a temperature of a measurement site on a skin surface of a subject, and a first temperature of the heat source, without contacting the subject and the heat source,
the second temperature sensor being configured to determine a second temperature of the heat source without contacting the heat source, and simultaneous with determination of the first temperature by the first temperature sensor, wherein when the first and second temperatures are simultaneously determined:
the measurement site is outside of the second field of view of the second temperature sensor, and
the second field of view overlaps with the first field of view at a location of the housing at which the heat source is disposed, the controller being configured to:
determine that the second temperature determined by the second temperature sensor is substantially equal to a maximum threshold temperature, and
based on determining that the second temperature is substantially equal to the maximum threshold temperature, determine whether the temperature of the measurement site determined by the first sensor is less than or equal to the second temperature determined by the second temperature sensor.
