Abstract
The invention relates to a device and a method for heating and heat preserving of optical devices, in particular to a device and a method for temperature control of optical devices in operation at low temperature, which belong to the photoelectronic technical field. The device for heating and heat preserving of optical devices comprises a heater, a heat insulation layer, a waterproof coating, a cavity shell, a control circuit, a thermocouple, a heater lead and a thermocouple lead. Low-temperature heating of optical devices is controlled by the device and the method to enable the devices to operate normally in the low-temperature environment, and the problem that the optical devices cannot be used normally in severe environments is solved. Heating and heat preserving of the optical devices are automatically controlled by means of the control circuit to enable the optical devices to operate normally in a wide temperature range, and the device and the circuit have the advantage of wide temperature control range. The heat insulation layer I used for temperature isolation of the controlled optical device from an external environment, the waterproof coating is arranged outside the heat insulation layer and used for closing, and the cavity shell is used for packaging integrally, so that heating and heat preserving efficiency can be improved, and power consumption in heating and heat preserving is reduced.
