Reviewer 1 Report

This is an overall nice review on the interesting topic of polymer optical fiber interferometry for temperature sensor. It can be accepted for publication after the following comments are addressed.

1.       Is PFO (line 85) or POF (rest of texts)?

2.       In line 323, it should be Figure 5 instead of Figure 6.

3.       Please use a consistent unit for sensitivity for a fair comparison. I find different kinds of units throughout the manuscript: nm/C, pm/C, dB/C, degree/C, rad/C, and nW/C.

4.       For sensor technologies, it is also necessary to give response linearity, another critical parameter for its performance evaluation. Please also give these values if available from the literature. The authors may also add one column in Table 1 for linearity.

5.       In lines 467 and 480, where is Figure 9?

 

6.       Add one column for temperature sensitivity in Table 1.

Reviewer 2 Report

In a paper titled "Temperature sensors based on polymer fiber optic 2 interferometer"  author Malgorzata Szczerska presented an overview of scientific publications on optical (fiber-optic) methods of temperature measurement.

Although at first glance, the article seems to be of a popular scientific nature, due to a very rich bibliography, it can be an excellent introduction to familiarizing yourself with each of the measurement methods described in it, the design of sensors, etc. In addition, it allows you to recognize the current state of knowledge and existing research trends.

Therefore, I believe that this paper is suitable for publication, albeit after correcting the following editorial errors:

 

Page 1 line 9

I suggest replacing the term "a critical temperature value" with "a certain temperature value". Well, in physical chemistry, the term critical temperature is somewhat reserved for the description of phase transitions.

Page 1 line 16

I suggest replacing the term "of sensors are becoming" with "of sensors would becoming".

Page 1 lines 35-37

The information in this section establishes the aim of the paper. Therefore, according to the rules of writing scientific articles, they should be at the end of the Introduction chapter.

Page 1 line 38

I suggest replacing the term "fundamental characteristics" with "fundamental parameter". Well, thermodynamically speaking, temperature is a system parameter, not a characteristic.

Page 2 lines 59-60

I suggest replacing the term "chemically aggressive atmosphere" with "chemically aggressive environment".

Page 2 line 64

I suggest replacing the term " resistant to chemical agents" with " resistant to most chemical agents".

Page 2 lines 70-71

I suggest replacing the term " transmitters of various physical quantities" with " transducers of various physical quantities".

Page 3 line 99

I suggest replacing the term "ordinary routine" with "daily activities".

Page 4 line 146

This part of the sentence is incomprehensible "reinforcesingle mode singlei- or single mode". It needs to be reformulated.

Page 4 line 150

One should check this information "(Figure 2 d and f)" because the figures shown are marked only up to the letter "e". Moreover, it is worth analyzing the phrase pointing to these pictures.

Page 6 lines 210

There is no reference to Figure 4 in the text. This gives the impression that it is redundant.

Page 6 line 220

I suggest replacing "distinguishedphysicomechanicalical" with "distinguished physicomechanical".

Page 7 lines 272

Consider replacing “arm” with “beam”.

Page 9 lines 359-360

I suggest replacing the term "work works" with "works".

Page 9 line 370

There is no Figure 7c (Figure 7c) in the paper. This needs to be corrected.

Page 11 line 415

I suggest replacing the term “presensame" with "present same".

Page 11 line 425

Since a relative measure "sensitivity of 0.13 dB/°C" was used, it would be appropriate to provide information about the reference state against which temperature calculations should be made.

Page 11 line 448

I suggest replacing the term “fitness" with "matching".

Page 12 line 467 and Page 12 line 480

There is no Figure 9 in the paper. This needs to be corrected.

Reviewer 3 Report

Type of manuscript: Review

Title: Temperature sensors based on polymer fiber optic interferometer

Author: Malgorzata Szczerska

 The subject matter is appropriate for the Journal and the approach is of potential interest to the readers of the journal.

 

1.What is the main question addressed by the research? 

Fiber optic sensors have many advantages over mechanical and sensors. Monitoring of physical parameters such as temperature, and chemical concentrations.  

Therefore, this review study on the temperature sensors based on polymer fiber optic interferometer will be valuable. 

 

2. Do you consider the topic original or relevant in the field, and if so, why? 

The review topic is relevant in the field. 

 

 3. What does it add to the subject area compared with other published material? 

In fact, they discuss in this review on the technique which can significantly reduce production costs, the installation and use process will be easier.  

 

 4. What specific improvements could the authors consider regarding the methodology? 

I think, the methods section in this research paper guides readers to the core of the research and technology. 

 

5. Are the conclusions consistent with the evidence and arguments presented and do they address the main question posed? 

The summary and future perspective outline key findings about the research. 

 

6. Are the references appropriate? 

Author added many references However I propose adding more relevant references.  

Sensors (Basel). 2013 Oct; 13(10): 13076–13089, doi: 10.3390/s131013076 

 References 63, 114 need correction. 

 

7. Please include any additional comments on the tables and figures.
