Abstract
Described herein is a detector for detecting optical radiation, especially within the infrared spectral range, specifically with regard to sensing at least one of transmissivity, absorption, emission and reflectivity, being capable of avoiding or diminishing a cross detection between sensor areas, specifically between adjacent sensor areas, thus, avoiding or diminishing a deterioration of a measurement based on the at least one sensor signal.
Claims12
A detector (110) for an optical detection of an incident light beam (120), comprising
- a circuit carrier (130) designed to carry at least one layer;
- at least one absorptive layer (138), the absorptive layer (138) being placed on a partition of the circuit carrier (130), wherein the absorptive layer (138) is designed to at least partially absorb the incident light beam (120), wherein the absorptive layer (138) incorporates infrared absorbing pigments (144), wherein the absorptive layer (138) is or comprises an adhesive layer (142), wherein the adhesive layer (142) comprises an adhesive substance which is an organic adhesive, wherein the organic adhesive is selected from the group consisting of polypropylene, polyvinyl chloride, polyvinyl acetate, polysulfide, silyl modified polymer, polyester, silicone, polyol, polyvinyl alcohol, ethylene-vinyl-acetate, cyano-acrylate, polyacrylate, polyethylene, polyvinylpyrrolidone, acrylonitrile, rubber cement, recorcinol glue, and polyamide;
- a substrate layer (114), the substrate layer (114) being directly or indirectly adjacent to the absorptive layer (138), wherein the substrate layer (114) wherein the substrate layer (114) is at least partially transparent with respect to the incident light beam (120);
- at least one sensor area (122, 122′), the at least one sensor area (122, 122′) being placed on the substrate layer (114), wherein the at least one sensor area (122, 122′) is designed to generate at least one sensor signal in a manner dependent on an illumination of the at least one sensor area (122, 122′) by the incident light beam (120), wherein the at least one sensor area comprises at least two individual sensor areas (122, 122′), wherein adjacent sensor areas (122, 122′) are separated with respect to each other by a gap (126);
- and
- an evaluation device (150) designed to generate at least one item of information by evaluating the at least one sensor signal.
