Abstract
A monitor for measuring the temperature distribution of a product (12) including a plurality of ball lenses (14) lying in a lenticular array (18) across the product (12). A signal processor (22) is connected to a photodiode array (20). Each photodiode in the array (20) is connected by a separate optical fiber (16) to one of the ball lenses (14).
Claims12
A temperature distribution monitor for monitoring the temperature distribution of a product, comprising:
- an array containing a plurality of lenses extending across the product, each of said lenses collecting radiation from an area of the product;
- an optical fiber for each lens receiving radiation intensity therefrom;
- at least one photo detector array optically coupled to the optical fibers for receiving the radiation intensity transmitted therethrough and establishing signals indicative of the radiation intensity transmitted therethrough;
- and
- a signal processor connected to the at least one photo detector array for receiving and measuring said signals from each lens which correspond to radiation picked up by the lenses to monitor the temperature distribution of the product.
