A measurement device may include a bias source to provide a bias, a photodiode to provide a linear current based on an input optical power and the bias, a log amplifier to receive the linear current and to provide a voltage, and one or more processors to receive the voltage and to determine a measurement of the input optical power at an observed temperature. The measurement may be determined based on a photodiode current corresponding to the voltage, a dark current, and a calibration current. The calibration current may be determined, for a threshold power range, based on a first plurality of current measurements at a first temperature and at a plurality of optical powers, a second current measurement at a second temperature and at a first optical power, and a third current measurement at the second temperature and at a second optical power.

Measurement device

A defroster and a vehicle are provided. The defroster includes: a housing defining an air outlet; a heating device disposed in the housing; an air blower defining a blowing outlet and disposed in the housing; and an air duct defining a duct inlet and a duct outlet, the air duct being disposed between the blowing outlet and the heating device so that air blown out from the blower outlet enters the air duct via the duct inlet and goes out of the air duct via the duct outlet, then passes through the heating device to exchange heat with the heating device, and is discharged out of the housing via the air outlet, wherein an area of the duct inlet is different from that of the duct outlet.
